What is UHS-1 ?

"UHS-1" / "UHS-I" stands for Ultra High Speed - Class 1 and is a speed class for SDHC and SXDC cards.

UHS-I is the fastest category of card available today with 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"

A further speed class is also defined.
