Micro SD Card U1 Version

UHS-I Speed Version
There are three different speed grades for wholesale MicroSD Cards. The entrance level is class, the next level is UHS-I and UHS-III, then the final one is Video speed. Obviously, the speed is getting faster and faster. They have unique symbol to stand for each other. U1 (UHS Speed Class 1) uses “U” as brief symbol to identify Micro SD with UHS-I. In order to classify bulk memory cards, these speed classes are important to tell specific cards. UHS-1 Micro SD Card has a minimum writing of 10MB/s, but MRT usually can provide 20-30MB/s. In addition, the reading speed can be as fast as 70MB/s. With this fast speed, MicroSD in this type can cater for high-end camera, drone, 4K dash cam and many devices with high resolution. Therefore, we also call it Full HD MicroSD.
