Starting off with sequential read, we find the four-drive RAID 0 array topping the charts close to 550 MB/s. Second in line, we have the three-drive RAID 0 and RAID 5 neck and neck at 400 MB/s

Sequential write had the four-drive RAID 0 out in front again with the three-drive array not far behind through lower QD. When we move to higher QD, the RAID 5 array scales up and takes second spot on the chart.

Sequential write response was again at its highest with a single drive, following this, we have RAID 10 and the two-drive RAID 0 array.
