Lexar Professional NM800 Pro Heatsink 2TB SSD Review

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

The Professional NM800 Pro heatsink version produces a very good read score of 87.32MB/s when tested with the CrystalDiskMark 4K QD1 1thread benchmark, which is good enough to put the drive into second place in our results chart. However, its write result of 222.65MB/s isn't as strong, bettered by the majority of drives we've tested.

Looking at the benchmark result screens, we can confirm the official Sequential ratings of the drive of up to 7,500MB/s and up to 6,500MB/s for read and writes respectively with a best read test figure of 7,535.44MB/s and a best write result of 6,595.83MB/s.

That 7,535.44MB/s Sequential read test result is good enough to put the drive at the top of the tree in our results charts.

Using CrystalDiskMark's Peak Performance profile to test the drive we got a read result of 7,479MB/s which is identical to HP's FX900 Pro drive and just 5MB/s faster than Patriot's Viper VP4300. What these three drives have in common is that they all make use of InnoGrit's IG5236 controller.

As with the default test, using the Peak Performance profile we could confirm the official Sequential ratings of the drives of up to 7,500MB/s for reads and up to 6,500MB/s for writes.

Using the default Real World profile sees the drive towards the bottom half of the results chart with a read result of 3,497MB/s and 5,611MB/s for writes.
