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.
Our four-threaded 4K random read tests couldn't get close to the official maximum of 1,490K IOPS. The best figure we saw was 512,320 IOPS (2,098.48MB/s) at the end of the test run at QD32.
Random Read QD v IOPS compared.
At QD1 the drive sits in fifth place behind both Crucial T700 Gen 5 drives and two Gen 4 drives, HP's FX900 Pro and Lexar's Professional NM800PRO. The drive moves up a position at QDs 2 and 4. However, at QD32, the FireCuda 540 is the fastest consumer drive we've seen to date.
