RAID 6
RAID 6 uses distributed parity, with two independent parity blocks per stripe, and disk
striping. A RAID 6 virtual disk can survive the loss of two disks without losing data.
RAID 6 is similar to RAID 5 (disk striping and parity), except that instead of one parity
block per stripe, there are two. With two independent parity blocks, RAID 6 can survive
the loss of two disks in a virtual disk without losing data.
RAID 10
RAID10 is also known as RAID (0+1) or striped mirror sets. This array type combines
mirrors and stripe sets. RAID10 allows multiple drive failures, up to 1 failure in each
mirror that has been striped. This array type offers better performance than a simple
mirror because of the extra drives. RAID10 requires twice the disk space of RAID0 to
offer redundancy.
RAID 50
RAID 50, also known as striped RAID 5 sets, intersperses parity information across each
RAID 5 set in the array. This array type offers good read performance as well as
redundancy. A 6-drive array provides two striped three drive RAID 5 sets. Generally,
RAID 50 is useful in very large arrays, arrays with 10 or more disks. Like the RAID 1n
and RAID 10n array types, RAID 50 can handle multiple disk failures.
