RANDOM PERFORMANCE BENCHMARKS
4K RANDOM WRITE/READ
We precondition our enterprise SSDs using 100% random 4K writes at QD256 for two drive fills. Performance data is recorded every second. We track this data to monitor the enterprise SSDs transition to steady-state and to verify that steady-state conditions are achieved before initiating queue depth testing. Steady-state is established after a full drive fill and the average steady-state 4K random write performance is approximately 1100K IOPS.
Listed specifications for the Memblaze PBlaze7 7A46 Gen 5 SSD is 1000K IOPS for sustained random write 4K IOPS during steady-state operation, whereas our results demonstrated an average of 1100K throughout QD8 to QD4096.
Listed specifications for the Memblaze PBlaze7 7A46 Gen 5 SSD is 3300K IOPS for sustained random read 4K IOPS during steady-state operation and our testing met that rating. We would like to have seen that performance level off a bit sooner as one might typically see it leveling off at the beginning of QD512 rather than what we see above with the steady climb.
4K 70/30
The PBlaze7 7A46 demonstrates a rather impressive performance curve for large datasets, constantly competing with the Dapustor 6301.
4K 50/50
The Memblaze PBlaze7 7A46 pulled off an average performance result of 1400K IOPS through QD256-QD4096, which is very impressive for any 3-DWPD SSD.
