CARDS - What is UHS-1 ?

"UHS-1" or more accurately "UHS-I"  stands for "Ultra High Speed" - 1 and is a speed class for SDHC and SXDC memory cards.

UHS-I has a bus interface speed of up to 104 MB/s.

An SDHC UHS-I card will work in any SDHC compatible device at lower speeds, but to take advantage of the UHS-I speed, a UHS-I compatible device is essential.

An SDXC UHS-I card will work in any SDXC compatible device at lower speeds, but to take advantage of the UHS-I speed, a UHS-I compatible device is essential.

UHS-I compatible cards and devices are normally marked with the symbol below ,"UHS-I" or "I"
