Biwin Black Opal X570 PRO 4TB Gen5 SSD Review

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

Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.

128KB Sequential Read / Write.

Using this Sequential test, the results confirmed the official Sequential ratings of the drive of up to 14,000MB/s and 13,000MB/s for read and write respectively with figures of 14,289MB/s for reads (QD32) and 13,408MB/s (QD8) for writes.

128KB Sequential Read Performance v QD Compared

At QDs 1, 2 and 4 the drive sits in the lower half of the results table but at QD32 it rockets up the table to sit in second place behind the heatsink-equipped version of Crucial's T705.

128KB Sequential Write Performance V QD Compared

When it comes to the Sequential writes the drive sits in fourth place at QD1 but drops down the table a couple of spots at QD2. However, at QD4 the drive sits in the top spot, a position it also holds at QD32, both by quite a margin from the Crucial T705 (heatsink version).
