About RAID
RAID 50
This dual-level RAID type is created by using two or more equal-
sized RAID 5 arrays to create a RAID 0. The top level RAID 0
shares the load among the second-level RAID 5s, improving both
read and write performance. Parity, used in the second level
RAID 5s, provides efficient redundancy.
Note: Adaptec 2410SA does not support RAID 50.
