Here a lower score is better and I stacked all three of the results to get an idea of which drives have the best overall performance. On the full system drive benchmark things flip around some with the NM620 staying closer to the higher end drives and outperforming PCIe Gen 4 drives like the Rocker Q4.ĪS SSD’s standard benchmark is similar to CrystalDiskMark but I like to look at their file transfer test that times out how long it takes to transfer three different file types. The NM620 outperformed the NM610, SN550, and the Crucial P2 in the data drive benchmark but fell behind the higher-end focused drives like the P5 and the VPR100. Next, I went with PCMark 10’s disk benchmark tests that use real-world situations like excel and word files to test the drive's performance. The write IOPS were most of the reason the NM620 did well, for the readd IOPS it matched the NM610. But the P2 and P5 did both outperform it significantly here. The NM620 didn’t do too bad here, especially compared to the NM610 and a lot of the PCIe Gen 4 drives. This was an improvement compared to the NM610 and was also better than the other DRAMless SSDs in the test like the P2 and the MP400.Īlso in CrystalDiskMark 7, I took a look at some of the IOPS performance of the NM620 when dealing with random data at a 4k size with a queue depth of 32 and 16 threads. For the write performance, the NM620 came in lower at 2301 MB/s. This put it right with the other PCIe Gen 3 drives like the MP400 and well ahead of the NM610 that I previously took a look at from Lexar. Lexar has the NM620 listed as up to 3300 MB/s for its read speeds and in CrystalDiskMark 7 I saw 3223 MB/s which isn’t too far off at all. To start my testing of the Lexar NM620 I wanted to take a look at its sequential performance. ![]() This was just to confirm that the drive was running at the correct transfer speed and to also document the firmware revision that I tested with which was the V1.8 revision. Before jumping into our test suite I did want to check out the Lexar NM620 using CrystalDiskInfo.
