What does U3 mean on SD card?

U1 and U3 refer to the write speed of the cards. U1 can write up to 10MB/s while U3 can write up to 30MB/s. That's a big difference considering the size of most image and video files created by contemporary cameras.

Which is better U1 or U3?

Compared to the U1 Micro SD card, the U3 SD card has a faster data transfer speed. If you want to have a high write and transfer speed to record 4K Ultra-HD video, then the U3 SD card is the ideal choice.

What is the difference between SD card U3 and U2?

A U1 card offers a minimum write speed of 10MB/s and replaces Class 10. A U2 card offers a minimum write speed of 20MB/s and U3 offers 30MB/s. These, too, are on their way out thanks to the growing data demands placed by the rise of 4K video.

Don't get fooled! What is SD Card class 10 U1 and U3? how to pick the best sdcard for you
