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.
The official maximum 4K random read figure for the 2TB Seagate FireCuda 530 is up to 1,000,000 IOPS. With our 4-threaded testing, we couldn't get close to this maximum figure with a best test result of 414,047 IOPS at a queue depth of 16.
4K Random Read v QD comparison
At QD2, the Seagate FireCuda 530 is the fastest consumer drive we've seen to date for random reads. However, as the queue depth deepens the drive slips further down the chart until at QD32 it's sitting just inside the top ten drives tested.
