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.
Klevv's 2TB GENUINE G560 is rated as up to 1,400,000 IOPS for random reads. Using our 4-threaded tests we couldn't get close to that figure, the best we saw was 522,889 IOPS at QD16.
4K Random Read v QD compared.
In comparison to the drives around it, the G560 performs best at QD1 and QD4 where it sits fourth in the results tables. At QDs 2 and 32 it drops down to sixth spot.
