Western Digital WD Black NVMe SSD Review

Testing – Sandra & ATTO
Keep in mind for testing the advertised speeds for this drive are 3400 MB/s read and 2800 MB/s write.

Our first test is SiSoftware Sandra’s Physical Disks benchmark. We run both the read performance and write performance tests. Click on the images below to see the full-size results.

The read test yielded 3175.30 MB/s whereas the write score was 2736.29 MB/s, both of which are very close to the advertised speeds of the drive.

ATTO Disk Benchmark also measures transfer rates across specific lengths. ATTO uses RAW data, our transfer sizes ranged from 0.5 to 8192kb. ATTO is usually our definitive benchmark for solid state drives.


Here we see the drive maxing out at around 3380 MB/s for the read and 2859 MB/s for the write.
