Disk and Data Availability is important for systems administrators. There are different ways to implement. RAID or Redundant Array Of Independent Disks is one of the most popular one. RAID 6 is complex disk architecture which is used to protect against two disk failure. We have all ready examined RAID types in this following tutorial.

How Raid Disk Configuration Works and Information About Raid 0 , Raid 1 , Raid 5 , Raid 10

Advantage

Configuration of the RAID 6 is high fault tolerant. There is two disk spare which means we can continue to operate even two disks fails. This is useful for environments which needs long data retention periods.

Disadvantage

There may be some little disadvantages using RAID 6. Using two disk will require some parity management and compute. This parity management and compute will create some overload over disks and some latency.

There is also some ownership cost problem which means this RAID 6 will cost more than RAID 6 and other RAID solutions. We will need more disks to implement RAID 6.
