RAID 5 8k Random Read/Write
The 9361-8i tops out at 508,572 IOPS at 256 OIO, while the ASR-8885 reaches 538,099.
The 9361-8i provides lower latency at 8-128 OIO, but it loses the lead at 256 OIO.
The 9361-8i takes the lead in 8k random write testing with an average of 41,802 IOPS at 128 OIO. The ASR-8885 peaks at 64 OIO with 29,490 IOPS, but it falls significantly under higher load.
The 9361-8i provides lower latency during the test.
The mixed workload testing shows the cliff both controllers experience when we mix in a 10 percent write workload, though the ASR-8885 falls lower than the 9361-8i. The 9361-8i leads this test with the exception of the pure read workload.
We observed the same performance trend from the ASR-8885 in our mixed workload testing. The same latency penalty is incurred as we mix in more write activity, reaching 16ms with a 90 percent write workload.
