RAID 50 – Striping of Distributed Parity

RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides data reliability, good overall performance and supports larger volume sizes. RAID 50 also provides high reliability because data is still available even if two disk drives fail (one in the 1-3-5 data stripe, the other in the 2-4-6 data stripe, as shown in the example below).

RAID 50 logical drives on the FastTrak SX8300 consist of 6 or 8 disk drives.

The FastTrak SX4300 does not support enough disk drives to create a RAID 50 logical drive.
