RAID 50 characteristics:

• Groups

disks as one large virtual disk with a capacity of

-1) disks, where

is the number of spans and

is the number of disks within each span.

• Redundant information (parity) is alternately stored on all disks of each RAID 5 span.

• Better read performance, but slower write performance.

• Requires as much parity information as standard RAID 5.

• Data is striped across all spans. RAID 50 is more expensive in terms of disk space.

RAID Level 60 (Striping Over RAID 6 Sets)

RAID 60 is striping over more than one span of physical disks that are configured as a RAID 6. For example, a RAID 6 disk

group that is implemented with four physical disks and then continues on with a disk group of four more physical disks

would be a RAID 60.
