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 94K IOPS.
Listed specification for the SSSTC PJ1-KW3840P Gen4 SSD is 85K IOPS for sustained random write 4K IOPS during steady-state operation and this SSD exceeded that spec at 94K IOPS.
Listed specification for the SSTC PJ1 Gen 4 SSD is 850K IOPS for sustained random read 4K IOPS during steady-state operation and our testing came above that at 916K .
4K 70/30
The SSSTC PJ1 demonstrates decent 4K 70/30 mixed read/write results with an average of 294K IOPS.
4K 50/50
The SSSTC PJ1 pulled off an average performance result of 192K IOPS through QD256-QD4096.
