Top FAQs for SDXC Cards

 

The default formatting for cards up to 2GB is FAT16.

In recent years, memory cards have gained more storage capacity; 4GB and above. The file format FAT32 is now commonly used in memory cards between 4GB and 32GB.

If a digital device supports only the FAT16 file system you cannot use a memory card bigger than 2GB (i.e. SDHC/microSDHC or SDXC/microSDXC memory cards).

Integral memory cards of 4GB or more such as those in the CompactFlash i-Pro, UltimaPro and SDHC ranges are only supported by FAT32 devices and must be formatted to FAT32.

It is best practice to format the card in your device before use, CAUTION formatting a card will delete all data, please see your device manual.

"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"

A speed class is also defined.
