Seagate FireCuda 540 2TB Gen 5 SSD Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random write 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.

As with the random read results with our four threaded random write tests, we couldn't get close to the official maximum of 1,500K IOPS. The best we saw from testing was 487,369 IOPS (1,996.25MB/s) at QD16.

4K Random Write v QD compared.

Seagate's FireCuda 540 seems to perform better at deeper queue depths when it comes to random writes as it's the second fastest consumer drive we've tested at QD's 2, 4 and 32 and fourth fastest at QD1.
