Samsung 980 Pro with Heatsink 1TB Review

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

128KB Sequential Read / Write.

Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.

With these Sequential tests, we could confirm the official up to 7,000MB/s read and 5,000MB/s write figures. with the drive producing a peak read figure of 7,152.75MB/s (QD16) with writes peaking at 5,257.07MB/s (QD2).

128KB Sequential Read v QD performance comparison

The 980 Pro Heatsink version shadows the standard 980 Pro throughout our Sequential read QD testing.

128KB Sequential Write v QD performance comparison.

In our Sequential write tests, the Heatsink version of the drive leads the standard drive in QDs 1 and 2, but as the queue depth deepens the drives swap around with the standard 980 leading the way.
