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 485K IOPS.
Listed specification for the KIOXIA CD9P Gen5 7.68TB SSD is 450K IOPS for sustained random write 4K IOPS during steady-state operation and this SSD exceeded that spec at 485K IOPS.
Listed specification for the KIOXIA CD9PP SSD is 2600K IOPS for sustained random read 4K IOPS during steady-state operation and our testing exceeded that spec at 2758K .
4K 70/30
The KIOXIA CD9P demonstrates amazing 4K 70/30 mixed read/write results with an average of 1100K IOPS.
4K 50/50
The CD9P pulled off an average performance result of 860K IOPS through QD512-QD4096.
