A technology that combines multiple disks to increase performance or fault tolerance.
Short for Redundant Array of Independent Disks. A technology that combines multiple disks, using mirroring or striping to increase performance and redundancy, with characteristics varying by level. Common levels include RAID 1 for simple mirroring, RAID 0 for speed through striping, and RAID 5, which balances redundancy and capacity efficiency using parity -- the choice depends on the goal.
