Yak is called a hard drive from a computer. Details and just about the hard disk drive

Zharoznizhuvalny for children is recognized as a pediatrician. Allegedly, there are situations of inconvenient help for feverish women, if the children are in need of giving innocently. Todi dad take on the versatility and constipation of fever-lowering drugs. How can you give children a breast? How can you beat the temperature of older children? What are the best ones?

Good hour, dobie, my dear friends and readers. I got one one, but if he was doing it at the video salon, then she came to the new granny of rock 70-80. I went to my friend and said that I needed HADADE. Friend yak bi orazu didn’t sound and drink, move, hadde? Vona repeated again, if she had kicked her friend not to smoke, then the father went away and said that he had said to buy HADEDA.

HDD 160 GB is written on that folder. Well, my friend chuckled and said, well hard drive for the computer and directing it to the іnshiy store. Ale is amazing more tse. Yak onuchok mіg vzagalі send your grandmother on a hard drive? Well, what was the name of the oak tree?

Ale, what am I sick of? Let me tell you about the same HDD at the computer. You will definitely not have food if you want to buy one.

HDD (Hard Disk Drive) - computer hard disk. You can feel that in roses alternative name I will add a lot, for example "Winchester", "Vint", "Hard", "Zhorstkiy", etc. Adjustment of the price is necessary for the acquisition of your information, in addition, the operating system will be installed on a new basis, in a new way. Tobto. without hard disk do not spoil anything especially at the computer.

Hard disk є in a pre-construction dzherel memory and when the live life is turned on, all information is added to the new one, to the view from the shvidkoy operational memory... You can use this to save your files, photos, music, etc. Ale is very pristіy, so it’s not easy to forget about for greater safety.

I can already sense the food: “Why do I call him Winchester? Tse zbroya shooter! ". Really, how can you be a spilny annex of information and rushnitsy? On the right, in 1973, the company IBM released a hard disk model 3340, but for the spi-sound it was simply called "30-30", which meant two modules of 30 megabytes each.

Kerіvnik Kenneth Houghton knows spіvzvuchya 30-30 at the famous guntіvtsі. On the right, in the case that the set to the tsієї gvintіvka mali is also the markuvannya 30-30, the de persha figure meant the size of the caliber in inches (0.30 - 7.62 cm), and the other figure meant a lot of gunpowder in grains (it’s not a drukarska pomilka, but a world vagi), which is a zasipavsya cartridge (30 grain - tse approximately 1.94 grams).

For the slickness and the visibility, I will call it yak slang. Of course, American slang has not been victorious for a long time, but in us we are not going to live for a living, I wish more of it could be a little bit under the fast name "Vint".

Attach a hard drive

The name gizmo is a small rectangular box, but there is a small number of magnetic disks on one spindle, which are similar to those on a CD. First, the presence of a head, scho reads, yak and big on the magnetic plates, reads all the information. Well, naturally, є y іnshі warehouses, but I think that all the details are all the same.

The first robot is similar to the robot of grammar programming, only the reader does not have a head and does not twitch magnetic disks, if you want to see them just small.

Main characteristics of a hard disk

obsyag

Check your hard copy of information and you can save on new one. Years later, the memory of the new hard-boiled ones was raised, and the splinters from the whole are a real need. Since my first computer has a volume of 40 GB and I started with my head, now I have 2,000 GB on my computers and I have already scored half of it. You can see a part without tears).

Ale є is one trick. Wirobniks write a size, for example 500 GB, if you connect the Winchester to the computer, run a smaller volume there, here it is 476 GB. And kudi has grown to 24 GB? That is all simpler.

Virobniks round off the range of values, moving 1 GB - as 1000 MB, 1 MB - as 1000 KB, too. Look, how it stinks you are selling a disk with a volume of 500 million bytes and if it’s more for 1000, and then for 1000, then you will see 500 GB.

Alle, 1 GB is not 1000, but 1024 MB, so in 1 MB it is not 1000, but 1024 KB. The results come in at least 500 million per 1,024, and then 1,024 and we can accept our 476 GB in copies. I have about 140 GB on my disk with a size of 2 Terrabayti. Nice, right? Now you know Zagalom.

The fluidity of the wrapping

The productivity of the hard disk also depends on the quickness of the spindle wrapping. And what is more quickness, less productivity of a disk, less energy is needed and more energy is needed.

For laptops and out-of-the-box systems, it is more common to have a turnover rate of 5400 turnovers for gum, as it is cost effective for cich outbuildings. The speed of exchange of information from the men, the protection of the exchange of information from the freelance.

On stationary computers, hardy sshvidkistu 7200 rpm can be installed. It’s worthwhile, it’s obvious, because at the stationary, you’ll want to be worth more possession, good quality with such a high level of performance. Plus, to all, the computer is continuously connected to the outlet, which means that there will be no power failures.

I think there’s a large number of turns, I’ll drive 15,000, but I won’t look at them here.

Connection interface

And, of course, hard disks will gradually come to fruition and the roses will change. Let’s be surprised, as the roses are blowing.

IDE (ATA / PATA) - this is the name of a parallel interface from the fast speed of transmission up to 133 MB per second. But the season's interface is old and horrible with such a pink, no longer vibrate.

SATA - The last-minute interface, which is just as modern, as replacing the IDE. The Danish standard has a moment є three revisions of the bright shvidkistyu data transfers: SATA 1 - up to 150 MB / sec, SATA 2 - up to 300 MB / sec, SATA 3, up to 600 MB / sec.

USB - This standard can be used to modern portable hard drives, which can be connected to a computer via USB and can be easily used. Plus I will add this to the fact that you can use it without turning on the computer itself.

The first interfaces, such as SCSI and SAS, are not necessarily required for simple standardization.

Form factor

I have been sleeping here recently, but what is the form factor for hard drives? Everything is simple here. Tse deprive yogo gabariti. Size 2.5 and 3.5 inches. Je zvichayno th INSHI, ale they have povsyakdennomu zhittі nіhto not koristuєtsya abo zastarіli long time.

For laptops, insert 2.5 ", and in stationary computers 3.5". I think you won't overturn anything)

Well, the axis is nachebto and everything I want to tell you in the whole statty. Ale, I can already feel: "Why can't you tell me about the SSD?" My friends, I need to write about the SSD about the article, even more so it looks like we have a hard drive. I will write obov'yazkovo about the new one).

Beginning, Dmitro Kostin.

Hard drives are the middle of key components of a PC or a laptop. There is a lot of reason for storing all the indicators in the given accessories. Yakі rіznodydi hard drives presented to the hot market? What is the optimal vibrati from the point of view of the version of typical devices of a koristuvach device?

So also a hard drive?

A hard drive is the main tool for saving files on a PC or a laptop. Structurally, it is a magnetic plate, which is wrapped with a reading and recording element - the head. On the slang of lovers computer technology to be called "Winchester", "Gwent", "Hard". The specifics of the function of hard disks is that the head, which reads and immediately writes down, does not come into contact with the magnetic plate. The directors of the whole, as well as a number of other design features, adjusting the functions, and one of the best options for obtaining information can be seen.

A hard disk is a resource, on which, as a rule, it will be disassembled system files so that they are present in the structures of the OS, early supplements, ігор. Installation of PZ is practically dependent on the transfer of resources from Winchester.

Most modern computer models can be connected to hard drives. Laptops are more likely to have one hard disk spaced out - through the small dimensions of the attached attachments. At the same time, there is about the type (the specifics of the type are visible), the maximum number of the most often is the availability of the available slots on the PC, as well as the characteristics of the productivity of the computer.

Already, the hard disk is the most important hardware component of the computer. Our focus is on the basis of the criteria for the optimal choice of a suitable device for the PC. For the first time, it will be true for the ear of the classifications of winchesters.

Classification of hard drives

In such a rank, in some species there are modern hard drives on the market of computer technology.

Among the most popular types of devices is a computer's hard drive, which is shaped like a 3.5-inch form factor. Such discs can be wrapped at 5400 and 7200 rpm. Communicating "Winchesters" from the PC to get help for other new interfaces. Nayposhirenіshі - IDE and SATA.

Є Hard drives adapted for servers. The size is, as a rule, the same as in the PC, the protest of the wraps of such attachments on the food is about 15,000 wraps on the quill. Winchesters for servers are connected with the main hardware components most often via the SCSI interface, or the latest SATA or SAS standards can be added. A server hard drive is a completely superb setting, but it's not wonderful: computers, on which they are accumulating, are installed, after the service has been asked to service the keys of the company's digital infrastructure. state organizations, internet providers.

Assigned types of "winchesters" for installation in the middle system unit Chi server pc. Ale є y call hard disks. It connects to one of the computer's external ports - most often USB or FireWire. The function of the zagalom is similar to the one that characterizes the attachment of the internal type. The volume of a hard disk, which can be classified as a category, is usually close to 500-1000 GB. On the right, in the one that is similar to the type of annex, it is often victorious to change from one computer to the first great obsyagiv tributes.

Find hard drives adapted for laptops. The size is the smallest, below the "winchesters" that are installed in the "desktop" computers - 2.5 inches. The speed of a hard disk for a laptop is most often 4200 or 5400 wrappers for ghilin. Functions such as wincester SATA interface... It is characterized by a high style before the change of position, which is quite logical due to the specifics of laptop computers.

Among the technologically advanced types of hard drives - hard drives. Oh, in principle, it is possible to increase the class of outbuildings, so that in these structures there are no plates that collapse. Dani similar to the type of hard disks will be written to flash memory. Attachments of this type are yak perevagi, and incomplete.

A lot of provincial PC wyrobniks adapt their factory lines to the release of devices equipped with the most solid accumulators. This type Hard disks cost more, less, in the structure of the presence of elements, how to wrap around. However, the stench of some of them is characterized by a decrease in energy consumption, practically by more noise during robots, and by a smaller car. Of course, it can be said that the typical indicator for hard hard drives is 300-400 Mb / s, which is even more decent on the other provincial communal standards, which can be used by modern computers.

Interface

Successful the establishment of a harsh disk on a PC, there is a lot of reason to be hidden in the new necessary interfaces. The specifics of the most widespread standards of the commune for the market of computer technology are clear. It will be a good idea for a business building of a koristuvach and a type of Winchester, which is optimal for a new version.

Among the most popular interfaces for connecting new USB hard drives. With a wide range of communal standards, there can be performances new versions- 1, 2, and 3. Hard disk capacity can be stored without any problems due to its sophisticated technology. You can tell the 1st version of the interface that when you are on the screen, you can transfer data at 12 Mb / s, the 2nd guarantor will exchange files up to 480 Mb / s, 3 generations of the USB-interface will secure the display. It’s not just for downloading files, but also, for example, for instalation and software, it’s the most beautiful, if it’s the most beautiful USB interface, but the second is the most beautiful USB interface.

The current hard drive of the computer can also be connected behind an additional FireWire interface. It is characterized by a high speed of transmission - close to 400 Mb / sec. Vinyatkovo effective hour of robotics with video files.

Standards are easy to understand, as it becomes clear before the hour of installation in the PC to accumulate an internal type. Vvazhaєya is obviously old, the protest popular interface - IDE.

We can transfer data from shvidkist at close to 133 Mb / s. Extensions in desktop PCs are a lot of ways to achieve a large amount of rose, which is not optimal for the design structure of a laptop.

The SATA interface is the result of meeting the IDE standard. Allowing to transfer data from shvidkistu up to 300 Mb / s. It is characterized by the fact that it is stolen from a transcript. Actively vikoristovu, as well as good quality transmissions

The SCSI interface, which is what they mean, is the main boss on the servers. It is also characterized by a high speed of transmission of tributes, close to 320 Mb / s. Є modernized modification of the opened interface - SAS. Hard disk drives, which function for the hour of the last time, can not be exchanged for data on the storage space at close to 12 GB / sec.

Criteria for choosing a hard drive

Indicators of the interfaces we have developed are important criteria for every hour of vibration of a hard disk. We also sounded the low of the most important parameters - such as the speed of wrapping the elements of the device, the form factor. Ale nimovirnishe, in the aspect of choosing the optimal model of the device, the characteristic is the memory of the hard disk. There is a lot of sub-active parameter - a lot of corystuvachіv to give a pass to a bigger shvidkіs "Winchester", nіzh that in which it is possible to change great number file_v. However - all the same, it’s perche, I don’t have a lot of respect for koristuvachіv.

The most important aspect of the choice of "Winchester" is the reason for its nominal characteristics (for example, the consistency of these interfaces) may be the sum of the communal capabilities of the PC. Well, well, the hard disk of the computer is not technologically advanced, there is not enough technology to adapt to the latest standards on the motherboard of the PC. The key nuances of the "winchesters" and the hardware components of everyday computers are easy to understand.

The sum of the sizes is important

The food meant that hard discs grow in size. You can go, but the parameter is different row. But most of the time, it’s not original. On the right, if a hard drive is installed in a PC, or if the area of a laptop is displayed, it will be more difficult, as the size of the storage space will be small, and not optimal from the point of view of the space available in the structure of the device. Vona will be practically unhappy, since the gabarity appears to be great - Winchester simply does not fit into a computer.

Obviously, tsya regularity is characteristic of the head rank for laptops, so as to the problems with the hard disk space in "desktop" PCs, do not win (often through the availability of additional add-ons). The fact that new hard drives for a laptop are planned to be added is required by the nobility, which is the exact size of the current ones. By food we mean that in all types of computers it is widened in size with a 2.5-inch form factor. It is not necessary for mothers to use them, since in some laptop models hard drives with a size of 1.8 inches are installed.

Summity of communal standards

Let's get it together as well as the communal interface of Winchester and the PC motherboard. The main nuance here is the prominence in the versions of the data exchange standards. So, є three types It is important that the general standard of comunication is used, so we can accumulate it, and it’s also a sum of money. motherboard... You can go like this, buy an expensive corystuvach, so I will not be able to exchange data for the current SATA 3 standard, a hard disk (the price of such models can be close to 10 thousand rubles), but a computer cannot be readily available. Vlasnik PK, such a rank, can overpay sutta.

Those who use the Winchester and PC USB standards will also be able to handle it. Yakshko hard drive of insurance for connection via USB 3.0 interface, motherboard But since it is not adopted, the technological capabilities of the standard will also not be implemented in the whole world. As for the FireWire interface, you can say, well, you can buy a hard disk, but it can be used (the price of a device can also be decent - close to 8-10 thousand rubles), you need to change it, but a PC is in principle with it. Daniy komun_kats_yny standard standard for laptops, albeit on the laptop "desktop" PCs. Apparently, hard drives that support FireWire, make it smart as well with USB interfaces, and sometimes it is small, so you can add non-functional FireWire ports on a PC. Aleksey koristuvach, on the other hand, rozrahovuvav in the hands of a competitor FireWire - an effective robot with video signals, but you might not reject the good results of the Winchester robot.

Optimal distribution

Yak mi meant whische, obsyag yak is the main characteristic of such an attachment, like a hard disk, is also a sub-active parameter. Bagaty koristuvacham tsilkom vistachak, cleverly it seems, a few gigabytes of disk space, for example, as long as the stink is done with documents. Comus and hard disk per terabyte is rendered inadequate by the frequent distribution of multimedia content - video, photographs, music - on a new scale.

It is recommended to finish the optimal amount of the accumulator in a foldable fashion. Ale the concept of "more is more - more beautiful" - do not wait for the most beautiful option, I know, from an economical look. Can be used for an expensive, hard disk drive - 1TB. The number of terabytes will be such a rank among the ordered - but in practice it can hardly be half. At the same time, when buying a smaller one, a little cheaper than saving money, you can use it to improve the productivity of a PC or a laptop (for example, buy additional module OZP or a forced cooler for the processor).

For a number of IT-fakhivtsiv, a 500 GB hard drive optimal version for a large staff of a koristuvach. So, on "vіnchesterі" of a type of obscenity, it is possible to grow close to 100-150 yew. photographs good quality, іnstalyuvati close 100-150 happy Igor... As the owner of the PC is not a collection of photo masterpieces and not a gamer, then it’s not enough, but he wants half of the resource. Ale, at my own house, photographers and games, then quiet opportunities, like giving a 500 GB hard drive, maybe a shortage. At the same time, the Danish obsyag of "Winchester" is seen as one of the most optimal from the point of view typical buildings, which are the best in the world.

The speed of wraps

The most important parameter that characterizes a hard disk is the quality of the wrapping of the plates. It is possible to say that it is important from the point of view of the actual speed of transmission of the data, as well as the dynamics of processing by the operating system of the new files. As "Winchester" is victorious as the main one, to be at a new cost of the OS, on the new one is set by the programs that іgry, then more beautifully, as well as the analysis of the characteristic is twisted in yakomogh higher values. Yaksho koristuvach kupuє other hard the disk, signs of the leading rank of the selection of files, then the whole sense of the speed of the wrapping of the plates is not a good indicator.

Chim vische value of the indicator, tim dear nakuchuvach. At the same time, an overpayment for a large turnover is not necessary, although it’s not necessary, maybe, again, it’s not wanted. Winchester with a great shvidkіstyu wrapping discs typeє іtototno more noise, nіzh the one at which wraps are modest, and also characterized by great energy services. The optimal indicator for modern hard disks, with the most effective transmission of a large number of koristuvach is 7200 wraps per hilina.

Cache memory

Among the significant indicators of the productivity of the accumulator is the cache memory. After using the resource, the hard disk can be quickened by the operation of the file operations. The cache memory has the most frequent power supply algorithms to the quiet of the computer's resources. As soon as the data is from the cache, the Winchester doesn’t need any shukati in the space of the operative memory and the middle of the files. Chim more size cash-memory, tim more beautiful. Ale is recommended by experts, the optimal value of the indicator is 64 MB.

Chi is a big brand?

Chi є sense vibrate hard drive for the first time you use the brand? The thoughts of IT experts and those who are in charge of the drive are even more important. It’s a matter of recommendation to use a brand, as well as a glance at the number of accumulations, which is released by a specific virobnik. Some of the most positive characteristics of the Samsung company, the hard disk drive, the devices of the Korean brand can be overwhelmed. Deyaki IT-experts praise the brandy Hitachi, Toshiba, and do not vvazayut; The water hour is marked by the company market leaders. It’s a fact that it’s significant. The status of the leader of the highly competitive market of computer accessories is easy to not be given. Tsyomu, mabut, spriy visoka yakness of robbed goods.

Also, if we need a hard drive for a PC or a laptop, then we can start responding to the next criteria:

Rosemir (actually the head rank for laptops - it is not preferable, the general indicator is smaller, lower slots, the transfer for the distribution of hard disks, unacceptable - the higher is the larger);

Standards that can be adapted (importantly, for the technological interface on the "Winchester", the whole world will have a lot of PC resources);

Volume (sub-active, ale 500 GB is the optimal indicator for a large number of employees);

Wrapping speed of plates (optimally - 7200 wraps per quill);

Cache memory (optimal - 64 MB).

Bazhano is also, winkster boo vypusheniya formy-virobnik, as being on the leading positions on the retail market in the general segment of annexes.

Nakopichuvach on a hard disk є, chi more than one of the found elements of the current computer. So, as a sign of signs in the first place for the pre-construction of your donations, you can get your money, files and files, so you can be saved on your PC. I will be even worse than Skoda, as it’s because I’m going to be angry, as a result of which you can spend all your tribute, as you will be able to quickly innovate. I must correctly operate and replace the element, it is necessary to be smart, and it’s a hard drive.

Check out the statistics about the hard disk robot, its component technical characteristics Oh.

Razvychay, the head elements of the hard disk is a spike of round plates with aluminum. On the view of the nasty disks, they are easy to bend, and the name was given to a hard disk. The stinks of some outbuildings are unimportant, and they are called fixeddisk. Even in the most conventional stationary computers, it is possible to replace certain models of laptops and tablets without any problems.

Malunok: Hard disk without top krishka

Notatka!

What hard disks are sometimes called - Winchester and how the stench can be worn out before the fire. In the 1960s, the IBM company released a shvidkisny at that time hard disk with the number 30-30. As a result of the meaning of Winchester's national health and that term, it’s not bargained for in computer jargon slang. And as a matter of fact, hard drives do not conceal anything special with reference winchesters.

Yak pratsyuє nakapichuvach on hard drives

Recording that information readout, which is located on concentric hard disk drives, broken into a sector, will help you to write / read it for additional universal heads.

Each side of the disc will transfer its own drive for recording and reading, the protector of the head will be rewritten on the drive for all discs. Tom heads move synchronously.

Video YouTube: Hard Disk Robot

It is normal for the robot to accumulate not admitting twitching between the heads and the magnetic surface of the disk. However, at the time of the power supply and the attachment of the head, the attachment of the head still sinks onto the magnetic surface.

It takes an hour for the robot to wrap the hard disk between the surface of the plate, and to wrap itself around the head, and a slight twist of progress is made with its head. As soon as a powder penetrates into the whole gap, or if it is prone to bend to the struma, it is great that the head sticks out from the surface to wrap around. A strong blow can cause head loss. As a result of this visit, there may be a few bytes, or the inconsistency of the annex. There is a reason to use the magnetic surface in the attachments of the magnetic surface, for which a special mastic is applied to it, which allows you to cope with the periodic strum of the heads.

Deyaky modern discs vikoristovuyut the mechanism of entangling / de-entangling, which allows the heads of the magnetic surfaces to navigate at the moment of connection to the electrical installation.

Formatuvannya high and low rivnya

Vikoristannya formatuvannya viskogo rivnya allowing the operating systems to create structures, so I will ask the robot for files and data to be stored on a hard disk. Effortlessly share (logical drives) the bailing sector volumes, two copies of tables, file distribution in the root directory. Behind the help of the above mentioned structures of the operating systems, it is possible to carry out the space of the disk space, the creation of the files, as well as the handling of the built-in files on the disk.

In other words, the formatting of the highest level is created before the shutdown of the disk and the file system (FAT, NTFS). Before the "fair" format, it is possible to remove the format from a low level, before the hour when the disk is loaded along the roads and sectors. Behind the additional DOS-commands FORMAT, a nasty disk can be used for both types of formatting, todi like hard format - if you don't have a high-level format.

In order to schob zrobiti low-level format on a hard disk, you need a victorian special programs, Nadaetsya nadaya companion-vyrobnik disk. Formatting dull disks behind the help of FORMAT transferring both operations, just like the ones with hard disks, which are assigned to the operations next to viconuvati okremo. Moreover, the hard drive is proud and the third operation is necessary mind for a victorian on one PC, more than one operating system.

The organization of several distributions is given the ability to install on the skin from them your own operating infrastructure with an enclosed volume and logical disks. Kozhen tom chi logical disc has its own letter of meaning (for example drive C, D or E).

Where to store a hard disk

Practically skinny modern Winchester includes the same set of components:

disks(їх number most often syagaє 5 pieces);

read / write heads(The number of most often 10 pieces);

actuator mechanism(Danish Mechanism will install the head as required);

dvigun disk drive(pristіy, scho to bring disks at the wrapper);

twilight filter(filter, roztasovani in the middle of the building of the accumulator);

handled the board with control schemes(for an additional component, the control is accumulated by the controller);

cables and roses(Electronic components of HDD).

As a case for disks, heads, the mechanism of the drive of the heads and the motor for the drive of the disks, most often a sealed box HDA is used. Zazvychay tsey box є The only other components that are not included in the HDA, before which you can enter the configuration items, the board and the face panel, are known.

Automatic parking of heads that control system

On the type of connection, the contact system has been transferred to the parking system. Necessarily because of the fact that I am accumulating tens of thousands of drives and descents of heads, so that I can read and read everything, it’s all guilty for specially introduced for cich dіy dіlyankas.

Before the hour of the last descents and descents, there will be inevitable abrasion of the magnetic ball. As soon as the wear is accumulated, you will be aware of the stress, then the hiring of the disk or heads will be found. In order to avoid any problems, they need to save up with a special mechanism of locking / unlocking, with a plate, as it is placed on the calling surface of hard disks. Tsei zahid allows you to lock the head and the magnetic surface to navigate at the same time. When the springs are connected, the heads accumulate independently on the surface of the stolen plate.

Trochi about the fortunes and the fortunes

Practically all hard drives have two filters: a barometric filter and a recirculation filter. Vidrіznyaє vishchezgadanі fіltri іnіnіuvanіh models, thаt thе victorious thаt іn thе accumulators οf older generation, those thаt thе smell іn thе middle οf thе corps аnd thіѕ substituted іt wіll not be transferred tο thе final operation.

Old disks vikorystovyvayut technology of post-distillation in the middle of the body and back, vikoristovuchi with a whole filter, which requires periodic change.

The dealers of the current accumulated about the scheme of the scheme were brought to the view, and that the filter of recirculation, which was removed from the hermetically sealed case HDA, would be deprived of the filter for filtering, when all the parts of the case were found in the middle of the case. Regardless of the success of the past visits, other particles still settle for bagatoraz "landings" and "evil" heads. Due to the fact that the body of the accumulator grows its tightness and in a new way it is pumped over, it’s the prodovzhu function to navigate in the minds of the obstructed middling environment.

Interface roses

A lot of everyday accumulations on hard disks are not provided with interface roses, which are used to connect the system to the system as a whole. As a rule, accumulate a minimum of three types of roses:

interface roses;

roses for giving live;

rose'єm for grounding.

On the other hand, I respect the merits of the interface roses, a bit of the stench that is used for rejecting / transferring commands and tributes. Bagato standards do not include the possibility of connecting several accumulators to one bus.

As soon as it was lost, it can be saved on the HDD with interface roses:

MFM and ESDI- Wimerly roses, scho vikoristovuvalis on the first winchesters;

IDE / ATA- roses for connecting accumulators, which most hour buv nyposhirenіshim through its own lack of partiality. The technical interface is similar to the 16-bit ISA bus. A further development of IDE standards with the adoption of a growing data exchange rate, as well as the emergence of possibilities without a priori return to memory for the additional DMA technology;

Serial ATA- Rose, having replaced the IDE, which is physically є with a single-line line, which is used for the last transmission of tributes. Being in the confusion mode, similar to the IDE interface, however, the presence of the "native" mode allows you to speed up with an additional set of possibilities.

SCSI- a universal interface, which is actively stored on servers for connecting HDD and other attachments. Uninvolved on good technical indicators, without becoming such an extension of the IDE through our road.

SAS- The last analogue of SCSI.

USB- an interface required for connection of call windows. The exchange of information in order to be used for the additional USB Mass Storage protocol.

Firewire- pink analog USB, the required connection of the external HDD.

Fiber Channel-Interface for high-class systems with additional high-speed transmissions.

Indicators of the quality of hard drives

Mistkist- Osyag information, so we will be able to accumulate. The total indicator for current winchesters can reach up to 4 terabytes (4000 gigabytes);

Shvidkodiya... The Danish parameter is without an average inflow per hour to the message and the average speed of information transmission;

Need- Indicator, which will start at the middle hour of the day on vidmova.

The exchange of physical abilities

The maximum amount of money, you can use a hard disk, lay down a whole number of factors, including the interface, drivers, operating system and file system.

The first accumulator of ATA, released in 1986, was interrupted by a lot, the maximum value of which became 137 GB.

The BIOS versions also changed the maximum number of hard drives, so systems that were configured before 1998, Mali - up to 8.4 GB, and systems that were built before 1994 - 528 MB.

Finding problems with the BIOS interconnecting a lot of accumulators with the ATA connection interface was too much, and its maximum value became 137 GB. Tse obmezhennya bulo podolano for the support of the ATA-6 standard, issued in 2001 p. Tsey standard having expanded the addressing scheme, scho, with its own circuit, has taken up a lot of accumulated storage up to 144 GB. A little more decision allowed to show off storage devices with PATA and SATA interfaces, for which information, which can be accommodated, is a designated enclosure of 137 GB.

Obmezhennya OS for maximum obsyag

Practically all modern Operating systems do not impose on such an indicator as the number of hard drives, which cannot be said about earlier versions of operating systems.

So, for example, DOS did not recognize hard disks, the number of which overwhelmed 8.4 GB, and there was only a small amount of access to accumulate in this type of list for additional LBA addresses, when there was a total number of addresses in DOS 6.x and early CHs.

The storage space of the hard disk is also similar to Windows 95. The maximum storage space is 32 GB. Krim tsyogo, innovations Windows versions 95 the FAT16 file system will be removed from the system, like, with its own charge, it will be added to the size of 2 GB for the size of the files. For a 30 GB hard disk drive, you need to add 15 parts.

Interchange of operations Windows systems 98 allow hard disk drives to get rid of a lot of money.

Characteristics and parameters

The leather hard disk has a change of technical characteristics, which is the only way to get started.

Nasamper, on the next step to beastly respect, so on the type of vicarious interface. Recently, a leather computer is more sophisticated and has a large shipment interface since Vikoristovuvati SATA.

Another not less important moment is the exchange of a vilny music on a hard disk. The minimum value is 80 GB, your maximum is 4 TB.

Another important characteristic of a laptop is the form factor of the hard drive.

Naybіlsh are requested in a wide range of models, the size of which is 2.5 inches, while in desktop PCs the size becomes 3.5 inches.

The spindle wraps are not cheap and fast, the minimum value is 4200, the maximum is 15,000 wraps for the gillet. All vischevkazanі characteristics are seamlessly injected onto the speed of the Winchester robots, as they rotate in Mb / S.

Hard disk robotics

More important are the hard disk indicators, which start:

Spindle wrapping, Vimiryuvannya which is carried out in turnover in khilina. Do not have to enter without the possibility of getting real quick exchange, you are not allowed to see a large scale attachment to a small scale attachment.

Access hour... The Danish parameter is calculated as the hour, which is taken by the Winchester, as the command is rejected before the information is transmitted via the interface. Most often the average figure is the maximum value.

Hour positioning of heads... It will take an hour to turn heads to move and install from one track to the other track.

Throughput capacity for the productivity of the disc before the hour of the last transmission of the great tributes.

Internal broadcasts of tributes for a quick information, which is transmitted from the controller to the heads.

The status of transmissions of donations for quick information, which is transmitted via the new interface.

Threes about S.M.A.R.T.

S.M.A.R.T.- utility, designed for independent conversion of the winners of the day, so you can use the PATA and SATA interface, personal computers with Windows operating system (from NT to Vista).

S.M.A.R.T. zdіysnyu pіdrakhunok and the analysis of the connected hard drives in every hour, right away, the operating system has been launched. In addition, when the analysis was carried out, the icon for the result of the diagnosis is displayed at the right code of the panel of the factory. On the basis of the results, the remaining hours of S.M.A.R.T. diagnostics, the icon can be entered:

On the cutting machine of the skin connected to the Winchester computer, we will add S.M.A.R.T. technology;

On those, if one or more of the indicators will not match the boundary value, if the Pre-Failure / Advisory parameters are set to zero. Food destination zhorstkogo's camp disc does not interfere with the transmission, however, how can winchester take revenge important information It is recommended that you often save on your hard drive in order to replace the HDD.

For those, if one or more of the indicators will not match the boundary value, with the same Pre-Failure / Advisory parameters, the value is not active. On the thought of hard disk drives, the whole set of information and information on such a winchester is not a matter of course.

Official of hopes

Such an indicator, like the hope of securing a Danikh є one with the best important characteristics hard drive. The Winchester factor is once in a hundred years, why you can go unimportant, so that the HDD can be used with the most over-the-top dashboard. At the same time, on the reliability of the skin disc, the mind is injected into the operation and itself is prone. Decals vyrobniki put on the market more "Syrian" product, and that doesn’t need backup copies, and it’s impossible to pay for Winchester.

Part of the price

On a skin day, the HDD service has been changed. So, for example, the current price of an ATA hard drive for 500 GB of storage is in the middle $ 120, approximately from 1983 r. Winchester Umnistyu 10 MB cost 1800 USD

From what has been said, it is possible to change the setting, but the HDD will continue to fail, and if everyone wants to be able to finish it, they can finish off the discs for reasonable prices.

Literally a few days ago, I went to school new hard disk for all non-limiting mass of megabytes, as you can get it on my computers.

After walking around the shops, it was easy to get rid of it and analyze it. The current country has changed, the price has changed before the writing of the book, it can be said, the zagalnuvalno-oglyadovaya statty.

It is not important: you will require more space for more information (grants the owners of HD video cameras!

NOTE: We are torn apart from those who are important for us - the wicked koristuvachіv, who don’t get lost in the report in the technical "kalamut". 😉

An hour doesn’t stand on the spot, everything changes, including in the industry of accumulating information. Old market leaders are changing ...

While there is a special development among the hard disk drives, they are not (in the sense of the quality of the product), but all the same, if they see the hierarchy among them, then the current leaders of the hard disk market, without question, are Western Digital and the company. Itself on the products of the cich firm is brought the least beast in service center that skarg on the side of koristuvachiv.

Let's go Fujitsu, Hitachi and Seagate. And most of the problems are spurred on by the Seagate accumulators (judging from my special practice and information from the latest services from the service centers).

You can easily change your mind. Just go to google, and enter the "Seagate problem" on the console, or "Seagate does not have a disk", the result will be enough ...

If you share everything behind the first item (virobnik), then the most recent purchase has been made - all models are from Samsung and WD. Price of the most problem-free discs.

The step-by-step parameter behind the list is obsyag.

When buying a hard disk drive, you should start with the following formula:

price / number of gigabytes,

... or in other words - the rate of one GB.

If you don’t need a lot of disk space, then you don’t have to respect the point. Just bathe the disk of a small amount you need. If you want more space for less than a penny, then put up to the whole formula seriously, just cut it off. 😉

The prices are going to the store, but in the middle of this year by buying from the light price formula є 1.5 TB WD disks and 2 TB models (not all 2 TB models of the current year are equally cheap;

Important technical characteristics.

The E axis went to the head point.

Hard disk, more precisely, its mechanical part is a power resource. Zvychay, win to play 5 rocky, to that, by sending the term, it is recommended to replace the accumulator, because there is a ymovirnist yogo raptovaya vidmovi.

Slow down to wear, persh for everything, dvigun (which is wrapped with plates) and a block of magnetic heads.

Move in an hour to spend an hour, and the block of magnetic heads consumes its positioning accuracy, as long as there are pardons.

The reason for the heat is the hard drive itself. The heat is visible from the positioner of the magnetic heads block, and, as a matter of fact, the thermal imaging is very strong to lie in the form of the shrink-wrap of the plates. At the same time, when the hard drive is intense, the video is more warm.

ALE!

The problem of thermal imaging can be violated by installing a disc with a decrease in the speed of wrapping the plates!

Naybіlsh widenі on the current accumulative wraparound 7200 rev / hv. Ale іsnuyut accumulate, de the number of wraps is 5400 or 5900 for quilting, at the same time, thermal imaging is SIGNIFICANTLY LOWER (I would say once in two), lower for models with 7200 rpm.

You can remember that the decrease in performance is the wrap around the productivity of the disc.

I will say this: if you marvel at a specific test, then the productivity of the disks due to the decrease in speed will be less wrap-around, ale lishe on a little bit of vidsotkiv.

In practical terms, it means that you don’t mind the current growth in 7200 rpm and 5400 or 5900 rpm models. On the other hand, on the bitterness of the lowered performance, the wrapping around is to speak better than the thermal imaging and the less noise of the accumulator. More precisely, their noise is practically everywhere.

Fortunately, the “fashion” is the creation of such “green” disks, tobto. lowering the thermal imaging of the middle of the virobniks is trivial, the same is not the case for the “greens” - ni.

WD CaviarGreen, Samsung EcoGreen is thin. Disks of cich ser_y may be lower than thermal imaging and energosozhivannya.

I zupiniv my vibir on the first - WD Caviar Green. The reason for this is that the discs are able to survive the smallest strum for the hour of spinning, tobto. The disc can spin up more and more before the start hour, but then it will decrease as soon as possible for the drive.

Yak vіdomo, dvigun use in the main pіd hour unscrewing the package of plates, and not if it is just pіdtrimu ruh.

Also, from the "trick" of the green discs, you can name the fixed shaft not from below, but from above. This allows you to minimize the amount of vibrations on the disc (for example, from the DVD drive).

For the sake of accuracy, I recommend taking a look at the animation from the WD website : http://wdc.com/en/flash/index.asp?family=stabletrac .

The axle of the winding disc:

Ale same tsikh disks є one dine Ale:

With new operating systems Windows Vistaі 7 accumulated work immediately, and the axis of work is normal in Windows XP, it is necessary to check the actions, about how to appear on the official website : http://wdc.com/ru/products/advancedformat/index.asp .

On the offensive screen, the process is shown on the disk itself:

When I put the disk on Windows 7, I didn’t get any specific details.

I can’t help but be aware of the fact that it has already been brought in immediately after the installation, and why I can’t help but be happy at once.

* Disk temperature per hour of the robot, three times per room (outside +28 +30).
* Noise, as it is not paradoxical, come on! It’s not so easy to navigate the great hour of the drive.
* 1.5 TB will be not enough, but all the same - it’s worth completing a decent obsyag. Nareshty and de zberigati FullHD video from my video camera! 🙂

Z you buv Mikhaylo Zuєv, for the respect, that is a purchase!

A hard disk is required for the installation of an operating system, a program for the collection of small files of a koristuvach (documents, photographs, music, files).

Hard disks are built up in large quantities, as there is a lot of money to be stored, as there can be a lot of money, because it is possible to lay down the productivity of the whole computer and hope, how to lay up some of them.

Winery hard drives (HDD) may be a great deal, not high shvidk_st that part. The most popular є solid-state drives (SSD), ale the stink may mean a small amount of money and cost a lot more expensive. An industrial option among them is hybrid disks (SSHD), which may be a sufficient amount of hard disk space, which are less expensive and more expensive.

Western Digital (WD) hard drives are most popular. Nice SSD drives viroblyayut: Samsung, Intel, Crucial, SanDisk, Plextor. You can see the budget options: A-DATA, Corsair, GoodRAM, WD, HyperX, so they will have the least problems. Hybrid drives (SSHD) produced by Seagate.

For office computer, which is important for robots with documents and the Internet, to deliver an extraordinary hard drive from an inexpensive WD Blue series with a volume of up to 500 GB. It is not optimal for today's 1 TB disks;

For multimedia computer(video, simple іgry) WD Blue 1 TB drive is more beautiful than vikoristovuvati as a supplementary one for saving files, and as a rule, install a 120-128 GB SSD, so it’s easy to speed up the system and the program to the robot.

For an іgrovy computer bazhano brothers SSD with a volume of 240-256 GB, on a new one you can install an іgor kіlka.
Hard disk A-Data Ultimate SU650 240GB

As a more economical option for a multimedia or gaming PC, you can add one Seagate Hybrid Drive (SSHD) with a capacity of 1 TB, it's not such a smart yak SSD, but it's still cheaper than a snazzy HDD.
Hard drive Seagate FireCuda ST1000DX002 1TB

Well, for a hard-working professional PC with a supplement to SSD (120-512 GB), you can take a smart and super-sized hard drive WD Black of the necessary size (1-4 GB).

I also recommend pribati yakisny call disk Transcend with a 1-2 TB USB 3.0 interface for the system and files that are important for you (documents, photos, videos, projects).
HDD Transcend StoreJet 25M3 1 TB

2. Type of disks

Modern computers have both classic hard drives on magnetic platters (HDD), as well as more solid-state drives based on memory chips (SSD). You can also use hybrid drives (SSHD), which are a symbiosis of HDD and SSD.

The hard disk is large (1000-8000 GB), but not very high (120-140 MB / s). Both can be used to install the system, as well as for the collection of files of a koristuvach, which is the most economical option.

Hard disk drives (SSD) may be somewhat small (120-960 GB), and even higher performance (450-550 MB / s). Stink is a lot more expensive and vikoristovuyutsya for the establishment of an operating system and action programs for the advancement of a computer's robots.

A hybrid disk (SSHD) is just a hard disk, to which a small volume has been added. shvidkoy memory... For example, the price can be 1 TB HDD + 8 GB SSD.

3. Storing HDD, SSD and SSHD disks

For an office computer (documents, Internet), it is enough to install an extra hard disk drive (HDD).

For a multimedia computer (files, simple games), you can put a small SSD disk on top of the HDD, so that the robot can create a system that is more efficient. It’s a compromise option between shvidkistyu and volume you can see the installation of one SSHD disk, which is much cheaper.

For a hard-working professional computer, the best option is to install two disks - SSD for operating systems, programs, and an extra hard disk for saving files.

4. Physical dimensions of disks

Hard drives for stationary computers may be 3.5 inches in size.

Solid drives for laptops 2.5 inches in size and hard drives for laptops.

In an extravagant computer, an SSD drive is mounted behind an additional special mount in the case of an additional adapter.

Do not forget to add, because it’s not included in the kit with storage, and your case doesn’t have any special mounts for 2.5 ″ drives. It is also practical for all modern cases and mounts for SSD disks, which will appear in the inventory as internal drives 2.5 ″.

5. Development of hard drives

All hard discs may be interface rose and rose vivid.

5.1. Interface rose

The interface is called a rose for connecting a disk with a motherboard behind an additional special cable (loop).

Modern hard drives (HDD) may be pink SATA3, which will increase the amount of older versions of SATA2 and SATA1. As long as the motherboard has old roses, do not use a new hard drive, you can plug it in and out of it.

And the axis for the SSD disk is bazhano, the motherboard is small, rose SATA3. If your motherboard has a rose SATA2, then the SSD drive will be half its performance (close to 280 Mb / s), but all the same is definitely more efficient than a snail HDD.

5.2. Roz'єm lively

Modern hard drives (HDD) and solid-state drives (SSD) may have the same 15 pin SATA ports. When the disk is installed in the stationary computer at the living unit, such a rose is to blame. As long as it’s dumb, you can choose a Molex-SATA adapter.

6. Amount of hard drives

For a dermal type of hard disk, it’s fallen asleep, it’s obsyag danih, as it can be vmishuvati, if we’re growing.

6.1. Volume of a hard disk (HDD) for a computer

For a computer designated for typing and accessing the Internet, the least amount of modern hard drives is enough - 320-500 GB.

For a multimedia computer (video, music, photos, simple games), there is a hard drive of 1000 GB (1 TB).

For a hard-working game or a professional computer, you can use a 2-4 TB disk (use your needs).

It is necessary to vrahuvati, well, the motherboard of the computer can handle UEFI, the operating system doesn’t have to pump the entire disk space for 2 TB.

If you want to improve the performance of the robotic system, if you are not ready to use an additional SSD disk, then yak alternative option You can view the add-on of an SSHD hybrid disk with a capacity of 1-2 TB.

6.2. Volume of hard disk drive (HDD) for laptop

If the laptop is victorious, it will be upgraded to the main computer, and there will be enough hard disk mnistu 320-500 GB. If the laptop is victorious, it is the main computer, you can know a hard disk with a volume of 750-1000 GB (it’s stored in a laptop).
HDD Hitachi Travelstar Z5K500 HTS545050A7E680 500GB

Also, a laptop can be equipped with an SSD drive, which can significantly improve the performance of its robots and system efficiency, or a hybrid SSHD drive, which is more expensive for an extraordinary HDD.
HDD Seagate Laptop SSHD ST500LM021 500GB

It is important to vrahuvati, as the disk drives will be read by your laptop. Disks of a 7 mm zavtovshka will become a model, and zavtovshki 9 mm can not be skirted, if such a vzhe vzhe vypuskayut nebagato.

6.3. Solid state drive volume (SSD)

So, since SSD disks do not get stuck for collecting money, then if you have the necessary capacity, you need to go out of that because the system will be installed on a new operating system.

Modern operating systems (Windows 7,8,10) provide close to 40 GB space for your robot that grows every hour of update. In addition, you need to install basic programs on the SSD, as it will not be very helpful. Well, for a normal robot on the SSD, there will probably be 15-30% of the free memory.

For a multimedia computer (files, simple games), the optimal option is an SSD with a volume of 120-128 GB, which allows, in addition to the systems and the main programs, to be installed on a new set of simple ones. Oscillations from the SSD need not only to see the folders, then you need to use the necessary programs and іgry rationally install the new one in order to speed up the speed of your robots.

Heavy modern games occupy a magnificent expanse. To that, for a hard-working game computer, you need an SSD with a volume of 240-512 GB, which is a must for the budget.

For professional workshops, such as video editing in high quality, but for the installation of a dozen of modern іgors, an SSD with a volume of 480-1024 GB is required, again, it’s still a lot for the budget.

6.4. Backup copy of the tribute

When you select the volume of the disk, it is also necessary to restore the backup copy of the files of the koristuvach (video, photo and in), which will be on a new basis. In the іnshom vypadku you rizikuєte rapt to absorb everything that you have accumulated in rock. This often completes not one great disc, but two discs of a small size - one for the robot, and one (can be called) for backing up files.

7. Basic parameters of disks

Prior to the main parameters of disks, which are often indicated in the price lists, the frequency of the spindle wrapping and the size of the memory buffer are indicated.

7.1. Spindle wrap frequency

The spindle can be hard drives and hybrid drives based on magnetic plates (HDD, SSHD). Oscillations of SSD drives are prompted by the memory chips, the stench of the spindle. From the speed of the spindle of the hard disk, to lay down the speed of the robot.

Spindle of hard disks for stationary computers, it is important that the wrapping speed is 7200 rpm. In some cases, models are developed with a quicker spindle wrapping of 5400 rpm, which is more efficient.

Hard disk drives for laptops can be easily wrapped in 5400 rpm spindle, which allows it to be quieter, less cold and less energy efficient.

7.2. Memory buffer size

The buffer is called the cache memory of the hard disk based on memory microcircuits. Tsei buffer of values for the acceleration of the hard disk robots, and even more vplya (about 5-10%).

Modern hard drives may have a buffer size of 32-128 MB. The principle of 32 MB is sufficient, although the difference in price is insignificant, you can take a hard disk with a large buffer size. Optimally 64 MB.

8. Shvidkіsnі characteristics of disks

For HDD, SSHD and SSD disks, we will be able to provide the performance of line reading / recording and hourly access.

8.1. The fluency of the line reading

The fluidity of the linear reading is the main parameter of any disk and the fluidity of the robot.

For extremely hard and hybrid disks (HDD, SSHD), the average readability is closer to 150 Mb / s. Hard drive hard drives with a speed of 100 Mb / s and less.

Solid storage (SSD) more readily and efficiently readable data from models, become 160-560 Mb / s. Optimal for the price / performance ratio є SSD disks with a performance reading of 450-500 MB / s.

If there are HDD-disks, then sellers in the price lists don’t mention these parameters, but only obsyag. Dal in the ts_y statty, I will tell you how to know the characteristics. With SSD drives, everything is simpler, so the shvidkisny characteristics depend on the price lists.

8.2. Linear recording speed

The price of the second line is the readability of the parameter, which you want to use for the couple. For hard and hybrid disks (HDD, SSHD), the speed of the recording is reduced to a fraction of the lower speed of reading and to look at every hour of vibration of the disc, some of them are importantly oriented to the speed of reading.

For SSD disks, I can record the speed of reading either in less mode, or in a simple way. In the price lists, the parameters are indicated through a slash (for example, 510/430), a large number means the speed of reading, the less speed of writing.

Dobrih slick SSD won get close to 550/550 MB / s. But in general, I’ll write down significantly less in flux on the speed of the computer's robots, not on the speed of reading. Yak budgetary option, trochas of lower speed are allowed, but not lower than 450/350 Mb / s.

8.3. Access hour

An hour of access to others for the importance of the disk parameter for reading / writing. Particularly strong hour of access is injected into the speed of reading / copying other files. Chim tsei is the lower parameter, tim is more beautiful. In addition, for a low hour of access, it is time to talk about the quality of a hard disk drive (HDD).

Good value for an hour of access for a hard disk drive (HDD) є 13-15 milliseconds. With a rotten indicator, the value is not more than 16-20 ms. As for those that are important parameters, I will also publish them in the statistics.

As for SSD disks, they have 100 times less access for them, not for HDD disks, so the parameter is nowhere to be applied, and it is not worth it.

Hybrid disks (SSHD) for the storage of additional built-in flash memory are within an hour of access from the HDD, as it is possible to download from the SSD. Ale through the enclosure of the flash memory, in the lowest hour I can only reach the files when they are brutalized, as it is most often the case to get through, as they were consumed in the flash memory. Name the system files, so I will not worry about the security of the computer and the high efficiency of the system, but not drastically pouring into the robot great programs that іgor, the odd stink just doesn't fit in the shared memory of an SSHD disc.

9. Hard disk virobniks (HDD, SSHD)

10. Wirobniks of solid-state drives (SSD)

Sered vyrobnik_v SSD disks have well recommended themselves:

Samsung
Intel
Crucial
Sandisk
Plextor

Yak big budget options can be seen:

Corsair
GoodRAM
A-DATA (Premier Pro)
Kingston (HyperX)

11. Memory type SSD

SSD drives can be encouraged on different memory types:

3 D NAND- Shvidka i dovgovichna
MLC- kind resource
V-NAND- average resource
TLC- low resource

12. Hard disk speed (HDD, SSHD)

All the parameters of SSD-disks we need, such as the amount of money, speed and availability, we can check the seller's price list and then get it for a price.

The parameters of HDD disks can be recognized by the model number or the part on the websites of virobniks, but for the best part, it is easy to do it well, because the catalogs are great, they may not be smart, they are called in their own way in the skin virobnik. English... That is why I will propose to you the best way, which I am repenting to myself.

A simple program for testing HDTune hard drives. You will allow the availability of such parameters as the speed of the line reading and access. Є without any entourage, as to conduct tests and victories in the Internet. In order to know the results of the test of this hard disk model, it is enough to enter the number of your model into the Google pictures or Yandex, which is indicated in the seller's price, or on the disk itself in the store.

Axis yak viglyadaє picture from a test disk for a joke.

Yak bachyte, on the ts_y karttsi the average speed of the line reading is indicated that the hour is viable access, as we are ts_kavlyat. Reverse only the model number on the picture with the model number of your disc.

Besides, behind the graph you can approximate the density of the disk. An inaccurate graph with great strikas that is a high hour of access to speak, bit by bit, about the inaccurate low-quality disc mechanics.

A beautiful cyclical or simply equitable graph without great strikes at a low hour of access to talk about the exact mechanics of the disc.

Such a disc is more beautiful, shvidshe that will serve better.

13. Optimal disk

Otzhe, what a disk or a configuration of disks vibrates for a computer in the presence of such a sign. At my glance, the most optimal will be the onset of the configuration.

office PC - HDD (320-500 GB)
multimedia PC cob ravine - HDD (1 TB)
mid-range multimedia PC - SSD (120-128 GB) + HDD (1 TB) or SSHD (1 TB)
igrovy PC cob ravine - HDD (1 TB)
Middle Rivne Game PC - SSHD (1 TB)
іgroviy PC of the highest level - SSD (240-512 GB) + HDD (1-2 TB)
professional PC - SSD (480-1024 GB) + HDD / SSHD (2-4 TB)

14. Part of HDD and SSD disks

At the end, I want to tell you about three beyond principles Vibor mіzh big mensh expensive models of disks.

The price for HDD-disks is the lowest to be found in the disk space and trochus in the virobnik (by 5-10%). It doesn't really save money like HDD disks. Bathe the models of the recommended virobniks, do not care and three dear ones, so that the stench will serve better.

The price for SSD-disks, except for the volume of that storage, is so much stale as a virobnik. Here I can give a simple recommendation - select the SSD you found from the list of recommended virobniks, which will take you for a long time.
