RAID 5 - Data Striping with Striped Parity

RAID 5 + Spare

In a RAID 5 + spare configuration, three of the disks use RAID 5, and the fourth is empty.

If any of the three disks fails, it is immediately rebuilt using the fourth spare disk. As a

result, you can remove the failed disk and still have the ongoing fast performance and data

protection offered by RAID 5. When the failed disk is repaired or replaced and re-installed

into the storage system, it automatically becomes the spare for the other functioning three.

You can use RAID 5 + spare only if your storage system has four disks. If the disks are not

the same size, the smallest of the disks determines how much disk space is available for

data, similar to RAID 5.
