Performance differences between RAID 5 and RAID 6
Because of the second parity data that needs to be generated and the additional reads and writes before conducting data, a RAID6 array is 10% slower than a RAID5 array. The RAID6 processing has been facilitated by Infortrend’s powerful ASIC400 engine and the performance tradeoff should be acceptable for those who desire a higher level of data protection.
