CrystalDiskMark

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 we see our 1TB 970 EVO delivering NAND-based lab records for both. Additionally, the 970 EVO's sequential read performance at QD1 is another lab record. This is what we are looking for most of all - random read performance at low queue depths. This is where performance matters most in an OS environment.

Overall, this is the second best CDM write performance we've seen from a flash-based consumer SSD. The write-centric SanDisk Extreme Pro remains our champion when writing data at low queue depths.

AS SSD

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, but Samsung's 970 EVO makes short work of it. Another lab record goes to the 970 EVO 1TB with a massive score of over 5,200. Keep in mind that this is our system disk and it is 75% full.
