Biwin Black Opal X570 PRO 4TB Gen5 SSD Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random read performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

Using our 4-threaded tests we couldn't anywhere close to the official maximum random read figure of up to 2,000,000 IOPS, the best we saw was 510,084 IOPS (2,094MB/s) at QD16 before the performance dropped back to finish the test run (QD32) at 510,031 IOPS.

4K Random Read v QD Performance Compared

At QDs 1 & 2 the drive sits in third place behind Corsair's MP700 Elite (heatsink version) and Phison's reference PS5031-E31T design. At QD4 it rises up to the top spot but by QD32 it drops down to sit in last place in the table.
