WD Red Pro 22TB HDD Review

The PCMark 10 Data Drive Benchmark has been designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.

The Data Drive Benchmark uses 3 traces, running 3 passes with each trace.

Trace 1. Copying 339 JPEG files, 2.37 GB in total, in to the target drive (write test).
Trace 2. Making a copy of the JPEG files (read-write test).
Trace 3. Copying the JPEG files to another drive (read test)

The 22TB WD Red Pro handles the rigours of the PCMark 10 Data Drive Benchmark pretty well with an overall bandwidth figure of 64MB/s.

There's hardly any difference in the PCMark 10 Data Drive Benchmark results between the 22TB and 20TB versions of the WD Red Pro. The most significant improvement is the access time of the new 22TB drive.
