Persh nіzh talk about those, like a memory card is smashed, next to a memory card, a USB flash drive and a memory card without a second. For the greater part, there is no obvious development, and we will not get into the details, it’s impossible to guess, but a USB flash drive, or a USB flash drive, is intended for use, exchange of data and often vicarious as an installer of children. A USB flash drive can be connected to a computer, whether I will attach it, such as a transfer of roses or an adapter for YUSB. Memory maps are rotated both on the basis of flash memory, as well as on the basis of other technologies and file systems.

If there are memory cards, then the stink of a great world is used for mobile attachments, such as smartphones, photo cameras, portable devices. musical center, videoorestratorio, pleєri and bogato іnshogo.

So also a memory card?

Memory card- a great accumulative pristіy, which vikorizovua for recording and storage of digital information, for example: photos, music, documents, programs іnshіh files.

The memory card allows you to expand the factory facilities to the annex - you can get great information about it.

Memory card formats

There are 3 formats of memory cards: SD, SDHC and SDXC, which are distributed in class (for quick transfer / reception of information), for memory and size reports. Briefly about the skin:

1. SD and microSD (Secure Digital Memory Card) - the most popular format, some of the best in all devices that accept SDHC or SDXC formats. One way, you can know Card Reader. Memory capacity up to 4GB.
2. SDHC and microSDHC (Secure Digital High Capacity) - not confusing because of the add-ons, but accept the format of the SD card. Memory capacity up to 32GB.
3. SDXC і microSDXC (Secure Digital eXtended Capacity) - the remaining type of memory card, which is the largest amount of memory up to 2 TB (2 Terabytes) and one hour by means of a memory card.

See memory cardsSDor їх form factor:

microSD- are miniature paintings of memory size: 11 X 15 mm. Victory is a memory card for your phone, smartphone, tablet or any other attachments.

miniSD- seasonal type of picture is less popular, lower microSD and larger size: 20 X 21.5 mm.

SD- The smallest view, size: 24 X 32 mm. Such pictures are victorious at the large and great annexes.

Klasi shvidkosti memory cardsSD:

It is not the least important criterion when choosing a memory card and the ability to record files and exchange information with attachments. The speed of the picture of the memory is shown for the speed of the recording of media files on the card, the quality of the production of music, of the volume of video recordings without the sound or the video is thin.

How much is the speed of SD cards?

Information about the speed of SD-cards can be found on memory cards, it is referred to in classes (SD Speed ​​Class), for example: SD Class 2, SD Class 4, SD Class 6, SD Class 10.

For the speed of memory cards can be rotated in special multipliers: 13x, 16x, 40x, 1000x and more.

The multipliers can be adjusted to the class of efficiency and equity, for example:

SD Class 2: write speed at 2 MB / s - multiplier 13x;

SD Class 4: write speed of 4 MB / s - multiplier 27x;

SD Class 6: write speed at 6 MB / s - 40x multiplier;

SD Class 10: recording speed of 10 MB / s - multiplier 67x; You can add the following symbols to the definition of SD cards:

V6 or Class 6: write speed up to 6 MB / s

V10 abo Class 10: write speed 10 MB / s

V30 or Class 30: write speed at 30 MB / s

V60 abo Class 60: write speed 60 MB / s

V90 abo Class 90: write speed at 90 MB / s

De, V (V Class) - ce Video Speed ​​Class, as you write down the video permissions. Class V guarantees minimum productivity for video recording. Such pictures can be used for expanding the memory of video cameras and digital cameras.

For the best SD-cards, use a 633x multiplier, allowing you to write to the card with a speed of up to 90 MB / s and a read rate of up to 95 MB / s. Christmas, є picture-memory, how to reinvent the quality of music in 6 times, see about pictures of the memory from the victors of the Ukrainian tire UHS-III. Pro tse below.

Insure also, for the right amount of money, it can be a bit lower, it is declared by a virobnik, and you must pay respect to those who do. What is so seen, you can learn from.

There are also SDHC 1 / SDHC 2 and SDXC 1 / SDXC 2 memory cards with advanced speed, which can be called UHS (Ultra High Speed). Such pictures are made on shvidshіy UHS tires. The stench in your house is to be in the class, which is represented by a number inscribed in the Latin letter U.

On this day, there are two such classes on UHS:

Class U1- Guaranteed speed of 10 MB / s;

Class U3- Guaranteed bandwidth of 30 MB / s.

Yak bachite, it is meant to be less than the threshold value of Class U1 / U3, tobto. go to the class to play with no cards, as in the turn of the week you can play bright shvidkistyu yak 10 MB / s, so і 100-300MB / s. There are two important points to talk about those, in this case, the speed, if for the sake of truth, if the claims are 10 or 30 MB / s, but not lower.

UHS can use the following icons that show the bus data:

UHS I- Write / read speed, order up to 104 MB / s.

UHS II- Write / read speed, up to 312 MB / s.

New type of tire for the current day:

UHS-III- record speed for writing / reading, up to 624 MB / s.

Yak vibrate memory card?

1. Before buying a memory card, in the first place, you will need to get a volume of SD-picture, which you need.
2. Viber the required card format, tobto. size, which goes to the memory card slot (microSD, miniSD, SD).
3. Get to know your attachment vimogi, as a zyomka that robot. Regardless of all, you can also vibrate the necessary class of performance, which is optimal for your attachment without galvanizing for an hour of photo, video, video transmission and transmission of data.
4. Offensive, male parameter, price additional possibilities SD-pictures, such as water impermeability, shock resistance, loss of temperature for an hour and so far. This point is often referred to professional operators, photographs or people who work in extreme minds, not transferred with extraordinary SD cards. For example, the SanDisk SDHC UHS I Extreme Pro memory card can be used at temperatures from -25 to +85 ° C. Such a map was stolen from drinking water, sleepy exchanges and blows. Such pictures are vikoristyuyutsya at the professional technology, at the children of the climatic minds from the Pivnichniy Pole to the Pivdenny Path. Such an SD card is very expensive, and I have a guarantee.
5. The remaining criterion, which for a bagatech will be virish, is the price of a card. Slide the number of SD cards as needed. Zrozumіlo, with some cards be ti, scho class vishche, mayut high shvidk_st transmissions of the tribute and the great obsyag of memory, ale varto memory, that such a picture can be insane with your attachment. So how great is the professional technique of making expensive memory cards for garnishing robots, and more easy attachments, such as telephones, mp3 / mp4-players and іnshі can be seen on SD Class 2,4,6 cards.

To brutalize respect! When choosing the right picture of the memory, emphasize the respect for the readings and write down. For example, it is not possible to record the speed of one picture, say Transcend, as it will be 100 MB / s, and the speed of reading the picture, for example, SanDisk, as it will have a speed of 160 MB / s. Some vyrobniki will introduce the speed of the record, the reading, the variety of different pieces of information.

Another commonplace, alright, happy, about how it is necessary to have a pamyatati - make a cup of cards only in re-branded stores, or some branded representatives, oskolki imovirnist darling for a gift in a big coin, and an overpayment for a great cards cost around 100-500 US dollars. And professional cameramen and photographs vzgalі vikoristovuyut all at once a number of cards.

For the purpose of focusing on the butt of the photo with symbols and short values:

Yaku memory card vibrate for the camera or video camera?

For great photography, video technology is already old enough to be old, even more so, that volume card, like the one used by virobnstvі since 1994, is CompactFlash. Multiplier Compact Flash can be 800x, 1000x, 1066x, and transmission speed up to 160 MB / s.

Such pictures wonderfully fit for mirror cameras, video cameras with high-quality cinematographic quality Full HD, 3D-Full HD.

For photos and cameras with HD quality, the best option will be UHS Speed ​​Class 1 (U1) cards, less than 10 MB / s.

For larger video cameras from recording Ultra HD 4K video, or 2K, it is better to use UHS Speed ​​Class 3 (U3) pictures, the speed of recording is not less than 30 MB / s.

In extreme cases, the option for recording video in Full HD (1080p) format can buy a memory card of the 10th class (Class 10) with a speed of at least 10 MB / s.

What class of memory cards are the nicest for a smartphone?

On the simplest smartphones, it is easy to notice the difference in memory cards, and for a mobile smartphone, as a rule, you can find a cheap memory card. Yaky class krashiy for new, strained ones, - tse even іnshe food, azhe the rest of the smartphones You may be able to take photos and videos from a single Full HD building (from 720p to 1080p / 1080i), and for all other pictures you need a minimum class of the 4th and 6th, with a speed of 4-6 MB / s.

Yak bachite, I will build everything up for the needs and possibilities of yours, it is easy to say unambiguously, like a memory card for a smartphone. 8+, for example, there is a lack of video information in 4K UHD (3840 × 2160) format, but for the whole, as you can see the video, you need an Ultra High Speed ​​Class 3 (U3) memory card because of the video quality. less than 30 MB / s. So, in general, ensure the characteristics of your attachment and the possibility of SD-cards.

The technology of SD-memory cards is evolving and increasing in size and speed, transmission of data and parameters, and at the same time the growth and price. SD-pictures for high-quality video capture from high-speed transmissions of 160 MB / s cost about $ 500.

Do not chase after the maximum performance of memory cards, as long as your attachment is the most simple function, for which SD-pictures can fit into a cheap segment. If you whisper an SD card for professional technology, then this is not a big deal of economy, even a camera with a separate Ultra HD 4K architecture cannot normally work with an SD Class 2 memory card at a price of $ 3.

Do you know you, which means the number 10 in the letter C, the one in the letter U and the number 300x on the card?

On mysku.ru Volodymyr Veretennikov (koristuvach Waldemarik) looking at MicroSD cards (http://mysku.ru/blog/ebay/29690.html) has written a treatise on the standard of memory cards and meaning. Allowing myself to touch it, I’ll look around the whole theoretical part.

Trots about the Secure Digital standard:

- SD 1.0 is the first standard, released in 1999 by SanDisk, Toshiba and Panasonic, as a direct competitor to the Memory Stick standard. The whole standard is theoretically mav on respect Amnesty accumulated from 8 MB to 2 GB. File system FAT16
- SD 1.1 - further enhancement to the standard, adopted in 2003 r. Three specialties - an increase in capacity up to 4 GB and a double increase in storage capacity. File system FAT16 / FAT32
- SD 2.0 (SDHC, Secure Digital High Capacity, Visoka Umnist) - was launched in 2006. for the nobility of deyakim old people of standards, zokrema, lack of amnesty accumulated. Zavdyaki danіy specіkatsії znyato zmezhennya in 4 GB and added to the class shvidkostі (Class Speed ​​Rating). Now you can open a picture from 4 to 32 GB. Also, the changes tricked the addressing schemes and the file system FAT32.
- SD 3.0 (SDXC, Secure Digital eXtended Capacity, expanded capacity) - accepted in 2009, the maximum storage capacity is up to 2 TB (from 64 GB to 2TB), 10 classes of storage added. In the new edition tho standard SD 3.01 introduced updates to the data exchange protocol (UHS-I), the data exchange rate for the interface is up to 104 MB / s. The exFAT file system.
- SD 4.0 (SDXC) - appeared in 2011 rotsі. As a matter of fact, a new data exchange protocol (UHS-II) has been introduced, as well as a low number of new contacts on the cards. The speed of data exchange for the interface is up to 312 MB / s. The exFAT file system.

Summity of cards and attachments of different standards:

Yak bachimo, old SD pictures can be accommodated in all attachments, the speed is mixed with pictures. Alle yakscho pristіy, projects only for SD cards (old photo / video equipment), insert an SDHC or SDXC card, attachment її just doesn’t beat. All standards have only straightforwardness (a little more old formats), the most popular SDHC card reader Kingston MCR-MRG2 (earlier in the kit with microSDHC with Kingston cards) do not add an SDXC card (another row in the photo, SDHC SDHC picture). Visnovok one, like a smartphone / phone / tablet / player / photo / video camera, etc. do not think of SD 3.0 podtrimki, do not change the SDXC picture. The attachments simply cannot be pampered! First of all, you can easily insert the old cards into the newest attachments with the SD 3.0 adapter without any problems, otherwise you will be interchangeable with the speed.

Small plate of classes microSD cards(mean minimum speed to record):

SD Class 2 - write speed not less than 2 MB / s
SD Class 4 - write speed not less than 4 MB / s
SD Class 6 - write speed not less than 6 MB / s
SD Class 10 - recording speed is not less than 10 MBs
SD Class 16 - write speed not less than 16 MB / s
UHS Speed ​​Class 1 (U1) - the speed of recording is not less than 10 MB / s, the theoretical speed is 104 MB / s, the speed can be either (new data exchange protocol)
UHS Speed ​​Class 3 (U3) - recording speed is not less than 30 MB / s (data exchange protocol updates)

Note: UHS Speed ​​Class should be deprived of annexes that adapt the UHS-I interface.

Often virobniks will give a rating of performance from a multiplier, for example, 13x, 40x, 300x, etc. How much can a multiplier translate to small MB / s? It is easy to multiply by 150, tobto. 1x = 150 KB / s = 0.15 MB / s. Resultі maєmo 100x = 0.15 * 100 = 15 MB / s, 300x = 0.15 * 300 = 45 MB / s. To whom іnki virakhovuvati, the axis of the most popular shvidkostі ratings:

13x - 2 MB / s
26x - 4 MB / s
40x - 6 MB / s
66x - 9 MB / s
100x - 15 MB / s
106x - 16 MBs
133x - 20 MB / s
150x - 22 MB / s
200x - 30 MB / s
266x - 40 MB / s
300x - 45 MB / s
400x - 60 MB / s
600x - 90 MB / s

Note: to the class of quickness, multipliers can be used indirectly. Most often, virobniks are so ranked to the speed of reading a picture, and the speed to write down can be quite different. Be sure to marvel at the class of performance, and then at the rating (multiplier).

Oskіlki our card will accept the UHS-I protocol, we will try to adapt it, so it will take (it is from VіKi):
Interface (protocols) shini danih:

UHS (Ultra High Speed) bus is a high-speed data exchange protocol, introduced in version 3 of the standard. Specifics of Vimaginality of cards and UHS controllers with large early interfaces on Normal Speed ​​and High Speed.
UHS-I interface (protocol) technical inventory Version 3.01. The speed of data exchange for the interface is 50 MB / s or 104 MB / s. Vikoristovuyutsya standard contacts, however, the sign of deyakykh kontaktіv was re-assigned for the implementation of a 4-bit data exchange.
The UHS-II interface (protocol) is designated in the technical inventory version 4.00. The speed of exchange is 156 MB / s or 312 MB / s. To the standard, there are two rows of contacts - 17 for a special picture 16 for microSD, a 4-bit exchange mode is available.
Regardless of the architecture of the providers, the maximum frequency for the UHS-I interface can be quite different. Tolerance standard two options: up to 50 MB / s (SDR50, DDR50) and up to 104 MB / s (SDR104). Architecture call for a blister (packing) picture. At the same time SDR50 mode interfase, tobto. Transfer rate up to 50 MB / s:

Є Attachments that support the UHS-I protocol, since they have a card to the UHS-I standard, they have all their capabilities, in this type of speed (the protocol allows data exchange up to 104 MB / s). Also, it’s old attachments, I don’t know about the UHS-I protocol (for example, it’s a third version of the SD 2.0 or SD 3.0 standard), so there will be deeds of shyness. There is a situation, a smart UHS-I card and a cheap card reader, which does not accept the UHS-I protocol. The rest is much more flexible, working in High Speed ​​mode (up to 20-25 MB / s), if the card is great for more (div. More photo modes). Bigger smart system of USB 2.0 / 3.0 standard. So, if the flash drive was running at the edge of its capacities at 8 MB / s on the other version, then having switched it on to the third, the increase in performance is not acceptable (well, insignificant). So and here (figuratively, for porvnyannya). It is not far off if you have “cached” on Maybut, and even 4K and 8K, but with current events, it’s necessary to put such a movie on the card. It seems that if your card is "sharpened" for a new specification, then it’s good!

Small plate for SD standards:

As far as the description of everything is concerned, all one didn’t sound, then it’s the same in simple words(don't go without a dance, :-):
Є special pictures, and є cards with UHS-I protocol (Roman numeral 1). І є attachments і from the standby, or without the support of the UHS-I protocol. As the element is not pidtrimki, it will be interconnected.

The butt axis is a pair of two identical microSDHC cards, but the only difference is to adapt to the UHS-I protocol (SD 3.01 standard):

In smart card readers with UHS-I support, the card is interconnected with Normal Speed ​​or High Speed ​​modes.

Also the 64 GB microSDXC picture Lexar (the situation is similar):

Nebagato about the markup of cards.

So, as the single standards are not marketed, all virobniks understand their cards in a simple way. Naybilsh is the correct markup of the card prices, it will be necessary to use them for the outbuildings with the UHS-I support and for the children. Frequency for annexes with UHS-I accessory is designated by the number 1 or 3 near the letter U. Fluidity for annexes is indicated by the number of middle Liter S.

Markuvan butt:

Toshiba microSDXC card (information content 3 out of 5). Yak bachimo, the meanings of the class of shvidkostі only for extravaganza (figure 10 in the middle of the literi Z), tobto. The speed of the wired attachments is not lower than 10 MB / s. So, as a card with a UHS-I interface (Roman number 1), it doesn’t show the class of services when connected to the UHS-I interface (number 1 in the middle of the letter U). I will record in the UHS-I mode for the smallest performance, no noise. The real speed of recording is also from the house. Natomist є Dodatkov іnformation іshodo svidkostі reading, not vishche 30 MB / s.

Dali microSDXC Samsung card(Informativeness 2 of 5). Yak bachimo, є offense to the class of scholarship that UHS-I specificity badge (roman numeral 1), ale the day of the dodatkova information about the schwidness of reading. In outbuildings with a UHS-I front door, you can change at wide boundaries, up to 104 MB / s. Here, I will write down the minimum speed in any annexes (with / without UHS-I support) not less than 10 MB / s. The real speed of the record is not a view. You can, the speed of reading is indicated on the packaging (blister).

More informative microSDXC Lexar (informative 3 out of 5). Є offense to the class of qualifications and the UHS-I specificity badge. As a matter of fact, 300x MAє means the speed of the record, which will display 45 MB / s. And what is the real shvidkist write down? It’s a pity it’s dumb. The virobnik knows a new trick (* Up to 45MB / s read transfer, write speeds lower. Speeds based on internal testing. X = 150KB / s), you don’t give anything “gucky” numbers 300x, you can’t write it quickly. Here 300x knowledge means the readiness of the reading. The real speed of the record by packaging is not recognizable.

Another microSDXC Transcend card (capacity 3 out of 5). Є offense to the class of performance and the UHS-I specificity icon, as well as the readability of 300x, which is 45 MB / s. I don’t know anything about the real speed of the record, besides, it’s not less than 10 MB / s.

Well, nasamkinets, legendary microSDXC SanDisk (informativeness 3 to 5). There is no class of shvidkosti for extra attachments (number 10 in the middle of the letter C), I want to pack є. Also, not a rating of quickness, I want the packaging of the presence Up to 45 MB / s (300x), the tests show close to 45/80 MB / s for writing / reading and the price in the area of ​​3.5 kilo rubles :-(, ale in the store z packing is not a problem.

Otzhe: why not one card has not rejected the informativity of 5 points? That is why virobniks are cunning and may even be expected to use readability (Up to 45-60 MB / s or 300x). For a large number of vipadks, it is important to write down the speed, it’s just like a high school student, but you won’t be a class, which doesn’t allow anything else (I’ll write down 10 MB / s for all the pictures). When shopping in a store, you can easily pick up and buy an item budget card I will write 10-12 MB / s for speed (two pictures with class U1 can be written from 12 to 45 MB / s). One of the head systems, price. There is only one visnovka, there is only one information on the map / packaging, and not to talk about the road, and before buying it is better to look at the testimonials of the Internet!
Before reading the text, I know about the class I will write down (the number is in the middle of the letter C), and it’s obscure about the speed with the letter "x" in the end. :)

Duzhe svyatkove reading. :)

(Secure Digital High Capacity) - a standard for flash memory cards (including options for changed sizes - miniSDHC and microSDHC), stylish telephones that іnshikh outbuildings.

Unimportant physical identity of the "extravagant" SD (without "HC") cards, SDHC cards There can be only little things in quiet outbuildings, the confusion of the SDHC is clearly declared a virobnik, while for such attachments it is more confusing because of the "extravagant" SD cards. Deyaki With the help of the attached attachments, you can restore the SDHC bootstrap to the new firmware from the stand-alone SD.

SDHC is viewed from its predecessor with a changed addressing scheme and the FAT32 file system, for which the maximum number of SDHC cards is 32GB. However qia file system I hate power - maximum size the file to be recorded cannot be larger than 4GB. Nadal, with the advent of SDXC, given a problem buffered by the transition to the exFAT file system.

The minimum volume of SDHC cards is 4GB, the "extra" SD cards of this size are in direct violation of the SD standard and may be confused. Be-like adjusting from the SDHC image to the image of the image.

Also for the SDHC, an understanding of the "class" has been introduced, and the numerical value of the minimum speed will be recorded, qiu card(Nayvazhlivіsha shvidkіsna characteristics of similar virobіv, it is possible to pour, for example, on the swiftness of the gray whale in children.) Tobto. "SDHC Class 10" means that this card can record data with a minimum of 10Mb / s speed.

(Secure Digital eXtended Capacity) - the upcoming version of the standard with the maximum card capacity of 2TB (two terabytes).

The industrial version of the standard, also called SD 3.0 or UHS104, describes a 64GB picture without a maximum speed of transmission of up to 90 Mb / s, which can be summed up. deyakim Free SDHC add-ons

Remaining version of SDXC, also called SD 4.0, has a theoretical maximum transmission speed of up to 300Mb / s, and the number of cards can be up to 64GB. With SDHC add-ons, the stink is not confusing.
The addition of SDXC support will also increase the support of SD and SDHC standards.
SDXC maps to the exFAT file system and officially supports the SDXC standard only for Windows Vista, Windows Server 2008 (the latest driver can be taken) і Windows 7. The set of drivers for Windows XP and Windows Server can be found. Mac OS X will accept exFAT from version 10.6.5. For Linux, there is a useful solution for robots with a common file system, and it is planned to add this support to the kernel to version 3.3.

I will write in SDXC cards for the definition of the quality of the UHS class. At the present moment, there are two generations of UHS classes - UHS Speed ​​Class 1 (U1) out 10 MB / s UHS Speed ​​Class 3 (U3) at 30 MB / s. One is sufficient for recording FullHD video, and the other for recording video in 4K format.

If you insert the SDXC card at the attachment, which does not follow the standard in advance, if you are informed about the need for the format of the card. All in all, there is no need for any robots, because of such an operation, you will bring the map to a non-standard camp.

Before starting to start using SD cards, for the current moment there are three memory cards:

Povnorosmіrna SD memory card.

І lowest size MicroSD

If you added a memory card with a smaller size, for example, a MicroSD card, and you need a MiniSD card, then you can easily correct the situation for an additional adapter. The adapter can also help you switch from MicroSD to MiniSD or SD.

If you want a memory card, connect to USB port, then you will need an SD-USB adapter.

Generation of SD cards.

At the time of this writing, there were three generations of SD cards:

SD memory card:

Rik vipusku z 2000r .;

Maximum capacity SD 1.0 - 8 MB up to 2 GB, SD 1.1 - up to 4 GB;

The Pochatkov file system is FAT16.

Comments: On this day, I’m morally stale, I don’t get caught up in it, I’ll get a little bit of it, and I’ll write it down.

SDHC (Secure Digital High Capacity) memory card:

Rik vipusku from 2006;

The maximum capacity is up to 32 GB.

The Pochatkov file system is FAT32.

Comments: Infectiousness is the most popular type of memory cards, it is tied with an indefatigable record of that obsyag. For a bagatech, the memory capacity is 16 GB and 32 GB, which is a completely acceptable, yet one unmatched plus, the low price of memory cards for the memory of the generation.

SDXC (Secure Digital eXtended Capacity) memory card:

Rik vipusku from 2009;

The maximum capacity is 64 GB. up to 2 TB (2048 GB);

Pochatkov's exFAT file system.

Comments: For multiple memory cards, images of 32 GB of memory, as there may not be enough SD memory ahead of the generation, no need to forget, so that it’s better to use it, and it’s possible to use the full size of the HD file, video. Read a lot of SD cards, but not only record video on them. high quality, and th zberigati yogo.

Miscellaneous SD cards.

On the next point, I think, there is a lot of zoos, so that the memory card can be stored from the SD card generation. For today's day, if you know a memory card up to 32 GB, there will be an SDHC card, which is more than 32 GB, then SDXC. If it’s stuck, it’s just a matter of fact that I’m going to vibrate the memory card. Below is the table, which will help you at the choice at the first column, the number of nose is indicated, at the other - a number of hilin vіdeo at the top one Full permission HD + number of pictures at the third column.

The speed of robotic memory cards.

Duzhe important characteristic memory cards є I will record the speed. You can record the data itself, as quickly as you can copy the data to the SD card, or as quickly as the program is written on the card, as well as the quality of the video, and you can record it on the memory card.

Five classes of memory cards are transferred by the SDHC standard:

I’m sure that progress isn’t worth it, the speed of the SD card robots is growing, for the class, I’ll understand the rating, who’s the best, I’ll write down the speed (multiplier 1 × = 150 KB / s).

Visually, it is easy to finish the class carti memory, for the whole to finish it respectfully pride yourself on the packaging:

For example, I want to talk about the madness of SD cards.

For attachments (photo video cameras, smartphones, etc.) SDXC cards, to see the robot, send SD, SDHC, SDXC cards. For annexes, go to SD, SDHC memory cards with SDHC cards. For SD add-ons, go away from SD cards.
