RAID 3

(Redundant Array of Independent Disks Mode 3) A disk subsystem that increases safety by computing parity data and increasing speed by interleaving data across two or more drives (striping). RAID 3 achieves the highest data transfer rate because all drives operate in parallel. Using byte level striping, parity bits are stored on separate, dedicated drives. Somewhat similar, RAID 4 uses block level striping but is not as popular. See RAID parity, RAID 5, RAID 0 and RAID.

With data striped across two or more drives, RAID 3 achieves the highest data transfer rate because all drives operate in parallel.
