The spreading of data over multiple disk drives to improve performance. Also known as "RAID 0," data are interleaved by bytes or blocks of bytes across the drives. For example, with four drives and a RAID controller that simultaneously reads and writes all drives, four times as much data is read or written in the same time frame as a system without striping. Disk striping does not provide fault tolerance but is often used in conjunction with disk mirroring (RAID 3 and RAID 5) to provide both speed and safety. See RAID 0, RAID 3, RAID 5 and RAID.
