• Higher performance than for RAID 6, especially during writes.
• Better fault tolerance than RAID 0, 5, 50, or 6.
• Up to 2n physical drives can fail (where n is the number of parity groups) without loss of data, as long
as no more than two failed drives are in the same parity group.
Dedicated spare
The dedicated spare drive activates any time a drive within the array fails.
Failure spare activation
Failure spare activation mode activates a spare drive when a member drive within an array fails using
fault tolerance methods to regenerate the data.
Assigning one or more online spare drives to an array enables you to postpone replacement of faulty
drives.
