A U1 Micro SD Card is a Micro Secure Digital (SD) card. It conforms to the UHS-I (Ultra High Speed Class 1) standard set by the SD Association. The "U1" speed class means the card has a minimum write speed of at least 10MB/s. This is enough for most uses, including recording Full HD video. Here are some key features of the Micro SD Card U1 Version: The U1 designation means the card has a minimum write speed of at least 10MB/s. This speed is enough for recording 1080p video. Capacity Range: Micro SD cards come in a variety of capacities, ranging from a few hundred MB to as high as 512GB or more. Use for applications that need continuous data writing. These include high-definition video recording, advanced cameras, smartphones, tablets, and more. Compatibility: U1 standard Micro SD cards are compatible with devices that support the UHS-I interface. File System: Typically uses the FAT32 or exFAT file system, depending on the card's capacity and the requirements of the device. The U1 class Micro SD card is a common memory card type. It is on the market for consumers who need faster write speeds than standard SD cards. But, they do not need higher UHS speed classes (like UHS-I U3 or V30).

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.

What makes the Micro SD Card U1 higher performance? It is UHS bus interface. This interface is a direct effect on speed, otherwise the maximum theoretical read speed cannot be as high as 100mb/s. This advanced technology can provide sustained data transferring, it can grantee write speed of 30MB/s, for instance. You may wonder UHS-1 MicroSD card can lead speedy transfer all the time or not. In fact, you need to get device supporting U1 if you need no loss on speed. Also, it is a backward compatible MicroSDHC card. So, you can use it in both high-end and low-end equipment. The difference will be performance. To experience the speed benefit, please make sure you get devices in real UHS interface.
