We used CrystalDiskMark 8‘s custom settings to test the drive's 4K random read performance through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

Samsung quotes a random 4K read figure of up to 1m IOPS for the 1TB 980 Pro Heatsink, the same as the standard drive. Needless to say with our 4-threaded tests we couldn't get anywhere close to that figure with a peak figure of 352,213 IOPS (1,442.66MB/s) at QD16.

4K Random Read v QD Performance compared.

At QDs 1 to 4, the Heatsink version of the drive shows much better performance than the standard drive due in no small part to the later firmware that the newer drive uses. However, at QD32 the situation changes around with the original drive giving better performance.
