RAID 0 (Redundant Array of Independent Disks Mode 0) A popular disk subsystem that increases performance by interleaving data across two or more drives. Data are broken into blocks, called "stripes," and alternately written to two or more drives simultaneously to increase speed. For example, stripe 1 is written to drive 1 at the same time stripe 2 is written to drive 2. Then stripes 3 and 4 are written to drives 1 and 2 simultaneously and so on. When reading, stripes 1 and 2 are read simultaneously; then stripes 3 and 4 and so on.Ironically, RAID 0 is a misnomer because there is nothing "redundant." If one drive fails, the entire RAID array fails. See disk striping, RAID 3, RAID 5 and RAID.
