Because they have marked several classes on SD card.
In this article, we are going to look at everything you need to know about SD card.
There is something very important that you should keep in mind that card reads speed and writes speed.
Reading speed is how fast card can transfer data to computer or your camera. Write speed is how fast card can write data came from camera or computer, in other word data storing speed of ards.
The first thing to consider is what card will really benefit for your camera. The best way to check this is to look up the camera’s specification on the manual. Other factors that you should consider whether you intend to use your camera for 4K video shooting or raw files shoot, it’s really important to go for a faster card if you use your camera for 4K or RAW files shooting and also make sure to check what card will support for your camera.
When you buy a SD card it’s really important to buy it from a reputable seller.

SD Card types
Generally, there are two types of SD cards: the First one is SDHC, stand for Secure Digital High Capacity, The second one is SDXC, stand for Secure Digital Extended Capacity. The only difference between these two is their capacity. SDHC cards are from 4GB to 32GB. SDXC is 64GB – 2TB.
If you use a point and shoot camera, a 16GB card is totally fine. However, if you use a camera like DSLR or Mirrorless, it’s really important to go for at least a 32GB or 64GB card. If you use your camera for bursts shooting or to record 4K videos, you will fill up 16GB card very quickly. So it’s really important to consider card capacity and it depends on how you will intend using your camera for.
Another important thing is that you should consider is that don’t put your all eggs into one basket. If something goes wrong with your card, your all images and videos are at risk. It’s a really good idea to use 3 or 4 cards rather than use only one 128GB card.
Today some cameras offer two card slots, that’s another reason why most people tend to use several cards.
SD Card Classes
Next, let’s look at their classes. This is the place where people are really confused. There are three classes which have introduced by the SD association. There are C-class, UHS-class and Video class.
C speed Class
What is the C-class? You may have seen a number inside a C latter on SD cards, such as 2, 4, 6 or 10. Those are the C-classes. Then, what indicates these numbers is that the minimum sustained write speed for cards.
Minimum sustained write speed of class 2 is 2MB/s, and a class 4 card is 4MB/s and so on. You can see these classes on both SDHC and SDXC cards. Normally, class 10 cards are sufficient for full HD videos. However, if your camera supports 4K videos, you want to go for the card that also shows their UHS class on.
Let’s look at what is the UHS speed class. This speed class was introduced by the SD association in 2009. If you tend to use your camera for 4K videos recording, RAW files shooting or burst shooting, this speed class is very important.
You can see this class on both SDHC and SDXC cards. UHS class symbol is a figure inside a U shape icon, such as 1 or 3. These numbers provide you the card minimum sustained write speed like C class.
Minimum guaranteed sustained write speed of 1 inside the U shape icon is 10MB/s and UHS 3 is 30MB/s.
You can also find numbers such as UHS- I or UHS- II. These are the UHS classes. UHS – II cards also have second-row contacts back of the card. If your camera support UHS – II, it’s a really good idea for go a one because these cards are very speed.
If you try to record 4K video for a slow card, it can be caused to stop recording.
Let say your camera provides 40MB data per second and you have a card which can write 20MB data per second. So that means it takes double times to write data to card which your camera provides.
Videos speed class
This speed class was introduced for 8K videos capability cameras. Generally, we called V Class for this video speed class.
It’s also like C class, can be understood easily. V6 card has minimum sequential write speed of 6MB/s. there are V class cards up to V90. V10 and V30 are for 4K videos, and V60 and V90 are for 8K videos.
Though these three classes, manufacturers use MB/s (megabyte per second) to show cards speed.
