Western Digital Black NVMe – WD’s Acquisition of Sandisk Made This Possible

HD Tune Pro

HD Tune Pro is a hard disk / SSD utility with many functions. It can be used to measure the drive’s performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.

Default Test (Read)

 

HD Tune Pro the default test shows us a minimum speed of 1056.5MB/s with a maximum of 1337.5MB/s and an average speed of 1331.9MB/s with an access time of 0.029ms. CPU usage is very good at only 1.6% (Approx).

Default Test (Write)

The Write test on HD Tune Pro shows us 755.2MB/s Minimum, 1345.5MB/s Max and 1329.1MB/s average with similar access times and slightly less CPU usage across the board as well. Unfortunately, HDTunes test load is not always “for every drive” as some drives are tuned for a more defined workload and in this case you can see how HDTune almost halves the performance we have come to expect from these drives.

File Benchmark Test

The HD Tune Pro File Benchmark tests give us some more true to life speeds as we have seen albeit still slower than we have experienced in other tests. It shows us the Peaked 4K Random Read IOPS which top out at 106,651 while the write IOPS are at 87,049
