There are tons of different types of memory cards out there, damn your leg to figure it out! I will try without water, only the most important thing! Read to the end, there are conclusions!

What memory cards are

Here are the 3 main and most popular types of memory cards - CF / SD / microSD

Here are the 3 main and most popular types of memory cards - CF / SD / microSD

SD memory cards

This type of card has 3 abbreviations - SD / SD_HC / SD_XC

This type of card has 3 abbreviations - SD/SD_HC/SD_XC
Secure Digital (SD) - the old format with a maximum volume of no more than 2GB, you cannot find such formats now, you can forget, because such a volume is small in any device!
Secure Digital High Capacity (SDHC) - already have a volume from 2GB to 32GB and these are the most common cards on the market!
Secure Digital Extended Capacity (SDXC) - New standard with memory capacity from 32GB to 2000GB and speeds up to 312 MB / s!

SD cards are plastic and tend to break and crumble! And it is very difficult to fix it if the case is broken. But if you use it through an adapter, then after breaking the adapter, replace it with another one and the card will live for a very long time!

MicroSD / MicroSDHC / MicroSDXC Cards

The adapter DOES NOT AFFECT THE SPEED of the memory card in any way! NO DIFFERENCE!

MicroSD is essentially the same as SD only in a reduced form! There is no difference between them, they work the same way and all designations are the same! This format has gained maximum popularity due to its prevalence in mobile devices (smartphones, tablets, players, etc.).

Adapter DOES NOT AFFECT YOUR WORK IN ANY WAY и MAP SPEED! And given the more versatile capabilities and widespread use of MicroSD, I recommend buying them, not SD! Because now SD can not be inserted anywhere except into the camera and the laptop!

You can use MicroSD not only in the camera but also in the phone and everywhere. For example, pull it out of the camera and insert it into the tablet and immediately look at it or show it to the customer if your camera does not have WI-FI!

 

SD and MicroSD designations

WHAT to look for when buying! And yes, there are still miniSD but this format is no longer used anywhere, you can forget!

Memory cards do not always write information about the card! I recommend not listening to the seller, but looking at the manufacturer's website!

  • Reading speed - yes yes, DO NOT WRITE !!! Namely reading! We do not need this parameter at all, it is important for us at what speed the data will be WRITTEN!
  • The write speed is usually always LESS than the read speed! And that's why it's MARKETING! The speed is high and it seems to us that the card is fast! But this is not the case!

For modern cameras (18-24 megapixels), I recommend taking 16-32Gb memory cards! It is better to change more often, otherwise if your one large 64GB flash drive glitches while traveling or on shooting, in order to shoot further, you will have to format and you nlose all data! But if you have 2 x 32GB, just change the card and shoot further, and restore the second one at home, it's very easy to do it at home!

As you can see, 90MB / s is proudly written on the package, but when studying the parameters, you can see that this is the read speed, and the write speed turned out to be low, only 40MB / s, which is not enough for modern cameras!
As seen 90MB / sec is proudly written on the package, but when studying the parameters, you can see that this is the reading speed, and write speed turned out to be low, only 40MB / sec that not enough for modern cameras!

If you are into photography, then write speed must be not less than 2-3 RAW files in 1 second! See how much your one RAW file weighs, open the USB flash drive on your computer and click on the file properties.

For example your RAW weighs 25mb, means 25 * 2 = 50 and the write speed should be not less than 50MB / sec... Do you often shoot in series? Then multiply by 3!

  • Memory card type. Usually SD, SDHC or SDXC stands for the maximum capacity of a memory card as described above.
  • Ultra High Speed ​​(UHS) bus - memory card interface in the camera. It affects the maximum speed of the card.

UHS-I - before 104 MB / sec

UHS-II - before 312 MB / sec

UHS III - before 624 MB / sec

A UHS-II memory card can be used with cameras supporting UHS-I, but the transfer rate will be reduced. To take advantage of the fast transfer rates of UHS-II cards, make sure your camera supports them.

  • Memory card speed class. Essentially a useless figure, you can not even look at it, it indicates that data transfer can occur from the mb / second chip, i.e. minimum speed. For example, "4th grade" means that the speed will be from 4mb / s, "10th grade" means that the speed will be from 10mb / s. Well, that is, from 10mb / s - it can be either 10 mb / s or 100 mb / s!
  • UHS Speed ​​Class (UHS Speed ​​Class) - Also not a very necessary parameter, it shows that the data transfer speed is up to 30 MB / s, thus providing support for devices with a higher quality video output.
  • The amount of memory available on the card. The size of your card, it makes no sense to take less than 16Gb, and it makes sense to take more than 32GB only if you are doing VIDEO.

CF (CompactFlash) memory cards

If you have an "old school" camera, for example Nikon D700 or some of Canon 5D, then you definitely know these large, thick, square memory cards, which are not used anywhere else at all, and in order to drain something from it, either connect the camera to a computer, or Card reader buy (very much I advise by the way).

The format is living out its time and will soon disappear as a class.

This type of memory card has its advantages, it is a higher speed, due to the built-in controller directly into the card (for SD cards, the controller is built into the camera and the speed depends on this too), but given the physical size of the card itself, and the fragility of the connection - soon she will disappear as a class in the future!

Here you only need to know one thing, the speed, which is indicated by a number and "X" next to it, for example 600X or 1000X. This parameter shows how many times the card is faster than the CD.

Keep in mind that CF is generally faster than SD, but price and size are disappointing.

There are adapters that allow you to insert the SD into a camera where the CF slot is. that is, insert the SD into the CF card and work! But alas, they all greatly reduce the data transfer rate, even if you have a fast SD, the adapter will greatly reduce the speed. And they are all like that, you won't find anything good. Therefore, if you have a CF car in a camera, either change the camera or buy a CF!

There are adapters, but they all work very slowly!

XQD cards

A new memory card format developed by Sony and introduced with Sandisk and Nikon. The fastest and most advanced type of memory card at the moment! But almost nowhere is it supported except for Nikon D4, D4S, D5, D850 and D500 cameras (these cameras have an option, when buying, choose which slot you want - XQD or SD + CF)

Perhaps the future belongs to them, but so far there is not a lot of tolu from them! And the price is huge!

Total

Only these cards are currently relevant on the market: MicroSD, SD, XQD and CF. And the most common and profitable is MicroSD. If you are taking photos, then the optimal one is 16-32GB. For video, I highly recommend taking 64GB.

Other types of cards

About cards Memory Stick Duo, MiniSD, CompactFlash Type II (CF-II), Cards CFast Cards etc . You can forget!

Which manufacturer is better to take?

In fact, it makes no difference! Everyone dies in about the same way! Better, of course, to prefer the more famous brands Sandisk, Kingston, Transcend, Toshiba, Sony.

Check what the maximum memory card size your camera can support! This is written in the instructions, and it's even easier to ask Google! Because older models sometimes do not support more than 32GB!

Save money

In shops "around the corner" such as "Svyaznoy" or "MediaMarkt" - cards are on 30% more expensive than on the internet! Always look at Yandex.Market the cheapest price!

safety

Any memory card can die at the most crucial moment! Therefore, if your camera has two slots for memory cards, make the second card - BACKUP!

More expensive models have 2 memory cards! use this!
More expensive models have 2 memory cards! use this!

Security

Do not carry all the photos with you, from past photo shoots!

  • A fotik can be stolen and your photos will not go where they should be!
  • While showing photos to a customer, you can accidentally show something obscene or very personal! It's not professional!
  • If you constantly pull the card out of the camera into the computer and back without formatting it, sooner or later it will glitch! And you will lose pictures! Take it as a rule - I HAVE COME from the shooting, HAVE SHOWN the pictures on the computer, with the COMP I HAS SHOWN it into the backup, put the USB flash drive back into the fotik and FORMATTED it!
  • At the right moment, the memory may not be enough if you have not cleaned the USB flash drive!
  • Format the USB flash drive ONLY in the CAMERA!

Just in case

Buy a very simple and cheap 32GB flash drive. And throw it in your bag "just in case", they often forget the flash drive in their computer, and come to the shooting without it! And so at least some will be with you!

Storing and organizing memory cards!

Do not throw cards at random and anywhere!

Spend 300 rubles on this useful thing!
Spend 300 rubles on this useful thing!

To know which cards are clean and can be taken, and which ones still have unmerged photos! YES and the cards will live much longer if they do not dangle and beat anywhere!
