Kingston’s new SDHC/SDXC UHS-I U3 card meets the SD Association’s latest specification, UHS-I U3 (Ultra High-Speed Bus, Speed Class 3), which guarantees performance of at least 30MB/s read and write.

The faster speeds ensure the best video and photo integrity by reducing stutter as well as faster PC upload time especially when using USB 3.0 card readers.
