So when you go to buy some, you must be clear as it is really called the exact type of card you want to buy, and it is best to call it by its real name that as I have indicated above is flash memory cards, followed by the type that According to their properties and characteristics.
The exact names that today have flash memory cards, are 3 Micro SD, SDHC and SDXC cards, these names or types of cards are a way to organize flash memory cards according to their capacity, ie internal memory You have, you can see the correlation between the name and its capacity below.
Type of memory card Micro SD according to capacity:
Cards up to 4 GB are called: Micro SD Card
Cards up to 32 GB are called: Micro SDHC Card
Cards up to 2TB are called: Micro SDXC Card
As you can see, Micro SD cards are somewhat more of the past, are memory cards of very little capacity or memory that have almost disappeared in favor of Micro SDHC and SDXC, which have much more capacity and work at higher speeds , Something very important because it directly affects the operation of your devices.
And since we get the subject of the speeds at which the flash memory cards work, let us know that these cards are also classified in one way or another according to their speed, for example Micro SD Cards are classified according to their speed of work.
Classification of Micro SD cards according to their speed:
Class 2 2 MB / s
Class 4 4 MB / s
Class 6 6 MB / s
Class 8 8 MB / s
Class 10 10 MB / s
Classification of Micro SDHC and Micro SDXC Cards:
UHS-I Class 1 (U1) 10 MB / s Real-time FullHD / 1080p video
UHS-I Class 3 (U3) 30 MB / s Video 4K / 2160p
As you can see the Micro SDHC and SDXC cards also have their own classification for speeds, if you want my advice on which card to choose, I would recommend that if you use a standard Micro SD card, do not use anything below class 10, and In the case of Micro SDHC and SDXC cards do not choose anything below UHS-I Class 1 (U1) class.
This way you will be sure to use a card with a minimum speed of 10 MB / s, I highlight the minimum speed, because even those classes can run much faster, such as the Samsung cards you see in the picture that work at 48 MB / s and what are UHS-I Class 1 (U1).
