Lexar NM620 Gen3 NVMe SSD Review


The SSD Review uses PCMark 8’s Storage test suite to create testing scenarios that might be used in the typical user experience. With 10 traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games, it covers some of the most popular light to heavy workloads. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices. After an initial break-in cycle and three rounds of the testing, we are given a file score and bandwidth amount. The higher the score/bandwidth, the better the drive performs.


PCMark 10 Storage Benchmarks produce an overall score as a measure of drive performance. Comparing devices is as simple as comparing scores. The tests also measure and report the bandwidth and average access time performance for the drive.  Each test uses traces recorded while performing real-world tasks such as booting Windows 10, starting applications such as Adobe Photoshop and Illustrator, working with applications such as Microsoft Excel and PowerPoint, and copying several large files and many small files.

In testing in both PCMark 8 and 10, we obsderved that performance results were consistently better and comparison charts of our storage would take some time.  We thought it beneficial to still post these results as they are very good.


We have put the Lexar NM620 NVMe SSD beside a few other Gen3 DTAM-less SSDs that we have just retested on the Intel Z590 Gen 4 Bench.   In our testing regimen, we load 40GB files of video, music, photos and OS onto the SSD and then move them to another folder within that SSD to test the maximum time for that transfer.

The Lexar NM620 falls right in line with where we figure it should and is not that far off the Samsung 980, both current Gen SSDs.


There was a time when most would say to stay away from DRAM-less SSDs and, once again with our testing today, we might suggest that time has past.  Both new gen DRAM-less SSDs tested within the past few weeks fared well.  The Lexar NM620 sports much that we like, highlighted by our first look at the new Innogrit NVMe controller which is fairly impressive with its 3300MB/s data throughput performance.

WE might suggest that pricing wuill settle just a bit and with the now standard 5-year warranty, we would have no problem whatsoever recommending the Lexar NM620.
