Hundreds of SD card manufacturers have produced thousands of memory cards and devices using SD standards. This has prompted SD memory cards to have multiple storage capacities, speed grades, and two sizes of SD card and microSD card. Since there are many types of SD memory cards to choose from; therefore, it is extremely important to choose the most suitable SD card for your automated machines, surveillance systems, personal computers, cameras, sports cameras, and other industrial applications, etc.

Speed and Capacity

Speed Class represents the guaranteed minimum read and write speed of the memory card, and is divided into two types: “SD Speed Class” and “UHS Speed Class”

SD Speed Class is divided into four specifications of 2, 4, 6, and 10, which will be indicated by the corresponding number written in the middle of “C” on the appearance of the memory card; UHS Speed Class is divided into two specifications of 1, 3, with ” Write the corresponding number in the middle of U” to indicate that the higher the value, the faster the reading and writing speed per second.
“C4” stands for 4MB transfer per second. In the UHS specification, “U1” means 10MB per second, and “U3” means 30MB per second.

And the speed of the memory card can be divided into:

Reading speed (R): it is the speed of searching files or returning files to the computer. The faster the speed, the faster the backup.
Writing speed (W): If you want to save files quickly, or require higher recording files, and you need to choose a memory card with a higher writing speed.
