Our Sequential read/write workload is centered on 128K transfer sizes.
Starting with sequential read, we noticed RAID 10 started to pick up steam once we hit higher queue depths, eventually touching 820 MB/s. RAID 5 managed over 600 MB/s while RAID 6 over 400 MB/s.
Sequential write, on the other hand, was nearly the same for RAID 6 and 10 while RAID 5 stayed near 650 MB/s.
RAID 5 started our workloads with random read results jumping off the chart. They are up over 2000 IOPS while Web Server is once again right behind at 1700 IOPs.
RAID 6 was almost identical to our RAID 5 results, but we did see a decrease in overall IOPS.
RAID 10 calmed things down a bit where we found random read just under 2000 IOPS. Web Server dropped just below 1500 IOPS, and random write was just touching 1000 IOPS.
