Samsung SM961 1TB M.2 NVMe PCIe SSD Review

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.







With this version of CDM, sequential performance is measured at QD1, which is the reason sequential rates are so much lower than the CDM we posted in our intro. This version of CDM measures performance at 512K, and again we note an unexplainable anomaly with the SM961. The SM961 is only able to muster 507.4 MB/s with 512K read transfers. This is far below that of the rest of the drives in our test pool. The SM961, as expected, sets a new lab record for sequential read/write performance with a spectacular 2823/1776 MB/s. Additionally, the SM961 another lab record at 4K QD4.




The SM961 sets two more lab records; sequential write and 512K write. The SM961 kicks out decent 4K random performance, much better than the 950 Pro at 4K QD4 and QD32, however, the OCZ RD400 and the Intel 750 deliver superior 4K random write performance.





Version and / or Patch Used: 1.7.4739.38088


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.






AS SSD is a demanding test, and the SM961 dispatches it with ease; setting yet another lab record. We are a bit surprised by this remarkable score and the fact that our long time champion, Intel's 750 1.2TB, is handily outperformed in this particular test by a tiny M.2 SSD with only two flash packages.
