Western Digital Black & SanDisk Extreme Pro 1TB M.2 Review (Page 5)

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 both of our test subjects delivering decent performance, but nowhere near that of the Samsung and Plextor contenders. However, at QD32, the WD drives lead the field.

Overall, this is the best write performance we've ever seen from a flash-based consumer SSD. Another lab record served up by Western Digital.

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 - that is unless you are running a Western Digital NVMe SSD. Yet another lab record for a flash-based SSD goes to Western Digital in spectacular fashion.
