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 Thread count – 4.
In our four-treaded 4K random read tests we couldn't get close to the official maximum of 1,500K IOPS. The best figure we saw was 511,768 IOPS (QD16) before the performance dropped back to 511,506 IOPS at the end of the test (QD32).
4K Random Read v QD Performance Compared.
At QD1 the Gigabyte AORUS Gen5 10000 sits in third place behind HP's FX900 Pro and the NM800PRO from Lexar. After QD1 the Gigabyte drive pulls slowly from the Gen4 drives, the biggest gap occurring at QD32.
