Biwin Black Opal X570 PRO 4TB Gen5 SSD Review

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.

Using a single thread the X570 PRO produced results that ranged from 25,968 IOPS (106.36MB/s) at QD1 up to 174,707 IOPS (715.224MB/s) at QD32. The drive's performance seems to begin to level off after QD8 with only a 580 IOPS improvement between QDs 16 and 32.

Using four threads, the produces a test result of 111,934 IOPS (458.48MB/s) at QD1 rising to a peak of 484,025 IOPS (1,982.57MB/s) at QD16 before falling back slightly to finish the test run at 482,820 IOPS at QD32.
