Samsung 990 Pro 2TB Review

Simon Crisp October 19, 2022 Featured Tech Reviews, Reviews, SSD Drives, Tech News

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.

Using our 4-threaded random read 4K tests we couldn't get close to the official maximum at QD32 of 1,550,000 IOPS. The best figure we saw was 356,356 IOPS at QD16.

4K Random Read v QD Performance compared.

Even though we couldn't get close to the official maximum speeds, the drive is the fastest we've seen to date at QD2. However, as the queue depth deepens the performance drops away.
