QNAP TS-439 Pro Turbo NAS
Aug 25th, 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 Read and Re-Reader results don’t even move compared to the RAID 5 results, we’re still at the 30MB/s range.
The Writer and Re-Writer results don’t take much of a hit. We’re seeing 18.3MB/s on the Writer and 43.8MB/s on the Re-Writer. This is a decrease of 1MB/s over the RAID 5 with Writer and an increase of 3MB/s on the Re-Writer.
