RAID 6

RAID 6 writes data across all disks in the volume and two parity blocks for each data block. If one physical disk

fails, the data can be rebuilt onto a replacement disk. With two parity blocks per data block, RAID 6 supports up

to two disk failures with no data loss. RAID 6 synchronizing from a failed disk is slower than RAID 5 due to the

use of double parity. However, it is far less critical due to its double-disk security.

A minimum of four disks is required to create a RAID 6 volume. RAID 6 offers very good data protection with a

slight loss of performance compared to RAID 5.
