RAID 10 - Combination of RAID 1 and RAID 0

RAID 10 is a combination of RAID 0 (performance) and RAID 1 (data security). Unlike
RAID 5, there is no need to calculate parity information. RAID 10 disk arrays offer good
performance and data security. As in RAID 0, optimum performance is achieved in highly
sequential load situations. Identical to RAID 1, 50% of the installed capacity is lost
through redundancy. RAID 10 will tolerate a drive failure of one drive per stripe. RAID
10 also requires a minimum of four drives and is set up by spanning two or more RAID 1
arrays. Up to eight RAID 1 arrays can be spanned in a RAID 10 configuration.
