RAID 50 characteristics:
• Groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of
spans and n 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.
