Our Sequential read/write workload is centered on 128K transfer sizes.
Looking at our sequential test results for our RAID 0 arrays, we found the two drive array to top out around 450 MB/s read with write results managing to reach close to 500 MB/s.
Adding two drives for a total of four in RAID 0, the array performance almost doubled up to 850 - 900 MB/s write with read performance coming in at a touch over 800 MB/s. Adding four more drives bringing our total to eight drives our RAID 0 array touched upwards of 1650 MB/s read and 1750 MB/s write.
Moving on to our RAID 5, 6 and 10 arrays, we first start with RAID 10 with four drives reaching just over 800 MB/s read and 450 MB/s write. RAID 5 was able to touch north of 650 MB/s write with read performance coming in at 650 MB/s as well. RAID 6 was quite close to RAID 10 with read numbers touching 450 MB/s with write around 430 MB/s.
Touching on RAID 50, we find read performance touching very close to 1300 MB/s with write performance going over 1300 MB/s at 1320 MB/s. RAID 60 too was rather good, reaching just shy of 1000 MB/s write while read was just over 820 MB/s.
