RAID 5 4K Random Read/Write
Write performance takes a huge hit with the RAID 5 arrays; the Reds average 149 IOPS to the 113 IOPS from the Seagate NAS HDD at QD256.
The read performance is comparable with results obtained in RAID 0, with an average 543 IOPS at QD256 for the Reds, and 410 IOPS for the Seagate NAS HDD.
Our write percentage testing illustrates the varying performance of each solution with mixed workloads. The 100% column to the right is a pure write workload of the 4K file size, and 0% represents a pure 4K read workload.
Both arrays experience a slope of degraded performance as we progress into heavier write workloads. This is an expected result of the RAID 5 write performance penalty. The Seagate NAS HDD exhibits less variability, though it does trail in performance. The gap between the two drives is significantly smaller in parity environments.
