CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using v8.0.

The later firmware revision in the Heatsink version of the SSD980 Pro seems to have given the drive a healthy kick in read performance over the standard drive while the write performance stays essentially the same.

Unlike the CrystalDiskMark 4K QD1 result, the Sequential read result of 6,775MB/s of the Heatsink version of the drive is a little faster while the write result is fractionally slower.

Samsung rate the Sequential performance of the drive as up to 7,000MB/s for reads and up to 5,000MB/s for writes. Using the Peak Performance Profile of CrystalDiskMark 8 we couldn't quite hit those maximums with a read result of 6,915MB/s with writes at 4,942MB/s.

The 4K performance is quoted as up to 1,000,000 IOPS for both reads and writes. We couldn't get close to those figures, the best read result we saw was 633,525 IOPS using the default Peak Performance Profile, while the best write figure was 522,627 IOPS from the 0 fill option.

Using the Real World Profile sees the drive sitting in the top half of the table with a Sequential read result of 4,141MB/s, with writes slightly faster at 4,252MB/s.
