PC Perspective Enterprise Test Suite – 8K Random
R/W performance scales as expected, with no unexpected dips. This is the sign of a well tuned controller and firmware that shows no performance drop at mixed workloads.
8KB write performance does very well here, fully saturating at rated write speed with a queue depth of only 8 and nearly saturating it at QD=4. 100% write latencies also come in the lowest of all operations, with a smooth transition (and corresponding added latency) as we shift towards 100% reads. Reads to take a higher queue depth to reach and exceed the peak rated IOPS of the P3608 – here it took QD=256 (128 per side) to exceed the rated 500,000 IOPS.
