A level of non-redundant Redundant Array of Independent Disks (RAID) in which data is striped across a logical drive or array. RAID Level 0 provides high input/output (I/O) performance and works well for non-critical data. All disk drives are available for storing user data; however, data redundancy does not exist. Data availability is more at risk than with other RAID levels, because any single disk drive failure causes data loss and a logical drive status of Failed.
RAID Level 0 is not actually RAID unless it is combined with other features to provide data and functional redundancy, regeneration, and reconstruction, such as RAID Level 1+0 or RAID Level 5+0.
