WebRAID 6 is an upgrade from 5: data is striped at a block level across several drives with double parity distributed among the drives.Parity information allows recovery from the failure of any single drive. The double parity gives this RAID mode additional redundancy at the cost of lower write performance (read performance is the same), and redundancy … WebRAID 5 is related to distributed parity. RAID 6 is based on dual parity. Applied techniques. RAID follows a combination of stripping and parity methods. RAID 6 uses both the stripping and parity methods.
