1.2.7 RAID 50
RAID 50 or RAID 5+0 is a combination of RAID 5 (distributed parity) and RAID 0
(striping). RAID 0 allows data to be striped and written to multiple drives
simultaneously, and RAID 5 ensures data security by using parity bits evenly
distributed on drives. Therefore, RAID 50 delivers higher data security than RAID 0
and better read/write performance than RAID 5.
Figure 1-7 RAID 50
1.2.8 RAID 60
RAID 60 or RAID 6+0 is a combination of RAID 6 and RAID 0. RAID 0 allows data to be
striped and written to multiple drives simultaneously. RAID 6 ensures data security
by using 2 parity blocks distributed evenly on drives.
