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.
Officially the 2TB Exceria Plus G3 is rated as up to 680,000 IOPS for 4K random reads. With our four-threaded tests, we couldn't get close to the official figure with a peak test result of 488,618 IOPS (QD32).
4K random read performance v QD compared.
At QD1 the drive sits plum last in the results table but as the queue depth deepens it begins to climb up the charts until at QD32 it sits inside the top 10 fastest Gen 4 drives we've tested to date.
