Jun 23rd, 2009 | By SimonRAID 6 is an extension of RAID 5 but far less common. It can recover from the loss of two disks and as a result there is an even larger drop in performance. However, seeing as we saw little difference in performance between RAID 0 and RAID 5, I’m already thinking that the performance drop will be minimal and RAID 6 should become an excellent option for those keen on speed but also data integrity.
The results are essentially identical, 34.4MB/s just like with RAID 5.
The same story can be told with the Re-Reader, we’re averaging 34.4MB/s.
The Writer and Re-Writer results don’t take much of a hit. We’re seeing 35MB/s on the writer and 89MB/s on the Re-Writer. This is an increase of 1MB/s over the RAID 5 with Writer and a decrease of 1MB/s on the Re-Writer.
