RAID 0 or Striped Set splits data across two or more disks, without redundancy.

RAID (Redundant Array of Independent Disks) Level 0 or Striped set uses two or more disks combined to act as one larger volume. The data is split or "striped" across each disk, increasing throughput. RAID 0 stores no parity information and thus provides no data redundancy: the loss of one disk in the set will result in the loss of the whole volume.

RAID 0 is commonly used in conjunction with RAID 1 to form RAID 1+0 (10) in what is referred to as a Nested RAID. RAID 10 is a striped set from a series of mirrored drives.
