The Class 10 card has a 10MB/s minimum data transfer rate, and features optimized recording performance with support for the FAT32 file system. It is compatible with SDHC and SDXC devices, but incompatible with standard SD-enabled devices / readers. The card features plug-and-play operation for simplicity. For added security, a built-in write-protect switch prevents accidental data loss. The card is constructed from non-volatile memory components and has no moving parts that might wear out or break. It’s been tested and is backed by a limited lifetime warranty, plus 24/7 live technical support.
