RAID 6 – Block and Double Parity Stripe

RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 disk logical drive can continue to accept I/O requests when any two physical drives fail.

The total capacity of a RAID 6 disk logical drive is the smallest physical drive times the number of physical drives, minus two.

Hence, a RAID 6 disk logical drive with (7) 100 GB hard drives will have a capacity of 500 GB. A disk logical drive with (4) 100 GB hard drives will have a capacity of 200GB.

RAID 6 becomes more capacity efficient in terms of physical drives as the number of physical drives increases.

RAID 6 offers double fault tolerance. Your logical drive remains available when up to two physical drives fail.

RAID 6 is generally considered to be the safest RAID level.

RAID 6 requires a minimum of four physical drives.
