That is RAID 1. It uses two drives with identical data so if one fails, you have the other drive.
One variation of RAID 1 used by certain controllers is to write as RAID 1 but read more like RAID 0 (but without the striping). That way, you have the write protection of a mirrored set, but can use the two drives to do interleaved reads for a read performance boost.

All USB flash drives (also known as thumb drives, pen drives, etc) are used as you would use the internal hard-drive inside your computer. Such flash drives come in many styles and capacities, and files can be written to, deleted from, and formatted as you would to hard-drives. It is advised that flash drives are unmounted before being removed to ensure all writing is complete and to avoid possible corrupting of the flash drive.
