RAID 5
(redirected from RAID 6)

    0.01 sec.
RAID 5
(Redundant Array of Independent Disks Mode 5) A popular disk subsystem that increases safety by computing parity data and increasing speed by interleaving data across three or more drives (striping). RAID 5 is similar to RAID 3, except that RAID 5 parity is distributed among all drives, whereas RAID 3 uses separate parity drives.

RAID 6
Similar to RAID 5 but not as widely used, RAID 6 performs either two parity computations instead of one, or it performs the same parity computation on overlapping subsets of the data. Using four drives, RAID 6 can recover from two failed disks. See RAID parity, RAID 3, RAID 0 and RAID.

RAID 5 - Speed and Fault Tolerance
With data and parity striped across three or more drives, RAID 5 has been a popular method for obtaining speed and safety.
