Version and / or Patch Used: 3.0 Technical Preview


CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy. Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at QD4. When evaluating CDM results, we focus on 4K random performance at QD1 and QD4.








Focusing in on QD1 and QD4 has the M8Se smoking the competing SSDs in our test pool except for Samsung's 960 EVO. Impressive synthetic performance to be sure. Although not the focus of our CDM testing, we will note the exceptional QD1 sequential read performance.




Like we saw with Anvil's, random write performance isn't the strong suit of the M8Se.






Version and / or Patch Used: 1.8.5611.39791


AS SSD determines the performance of SSDs. The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD. We evaluate AS SSD performance in terms of overall score. We are looking for a minimum score of 2,000 when evaluating NVMe SSDs.








AS SSD is a demanding test, and the 512GB M8Se handles it with ease - delivering a score that is up there with some of the best. If we focus on the read score, we again see that the 960 EVO is the only drive in our test pool that is capable of besting the M8Se 512GB. The 256GB model does not fare nearly as well. Overall, it only outperforms the Intel 600p. It does, however, deliver a better-read score than the SX8000.
