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.








The Polaris controlled (Samsung) SSDs display vastly superior sequential read performance where it matters most – QD1. Once again, the PM961 is nipping at the heels of the 960 EVO. We see a big difference between Intel and AMD when reading random data. The PM961 is flexing some muscle and giving us a glimpse of why we believe it to be the best value in flash-based NVMe SSDs.




The AMD Ryzen platform is at a real disadvantage in comparison with Intel when writing random data. The PM961 is delivering better random write performance than the more powerful SM961, for two reasons, the driver we used on the PM961 and its pSLC caching layer.






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 PM961 eats it alive, scoring over double our minimum of 2,000 on both platforms. The PM961 outscores the 960 EVO reading data, and the 960 EVO outscores the PM961 writing data. Overall, both drives deliver similar performance, but the PM961 is $85 bucks cheaper.
