RAID 6

March 10, 2011 by Igor Drobot Leave a Comment

A RAID 6 is another form of parity protection for disks. Called dual parity too.

Requirements: 4 Disks
Capacity: (Size of Smallest Drive) * (Number of Drives – 2)
Read: Very good read performance
Write: Poor write performance due to dual parity overhead and complexity

For this RAID level you should use a hardware controller.
