We used CrystalDiskMark 8’s custom settings to test the 4K 70/30 mixed read/write performance of the drive through a range of queue depths using a single thread and four threads.
In our 4K 70/30 read/write tests the SSD 9100 Pro peaked at the QD16 mark using both single and four threads, before the performance began to level off.
Using a single thread the drive accelerates from 28,971 IOPS (118.66MB/s) at QD1 up to 173,141 IOPS (709.18MB/s) at QD8. From this point, the rate of performance begins to slow, finishing the test run at 179,548 IOPS (735.42MB/s) at QD32.
Switching over to four threads the drive climbs from 117,868 IOPS (482.78MB/s) up to 480,141 IOPS (1,966.66MB/s) at QD8. The drive peaks at QD16 (491,839 IOPS, 2,014.57MB/s) but the rate of acceleration has slowed down. The drive finishes the test run at QD32 with the performance dropping back to 488,478 IOPS (2,000.81MB/s).
