2.2.2.5 Striping with Dedicated Parity Disk (RAID 3)

RAID 3

Minimum Disks required

3

Capacity N-1
Redundancy Yes

RAID 3 performs Block Striping with Dedicated Parity. One drive member is dedicated
to storing the parity data. When a drive member fails, the controller can
recover/regenerates the lost data of failed drive from the dedicated parity drive.
