In our throughput tests, the reads peaked at 287MB/s (4MB block) which is 19MB/s faster than the official figure although by the end of the test run the figure had dropped to 248.33MB/s. Writes peaked further back at the 1MB block mark at 278.30MB/s, also faster than the official figure before dropping back to finish the test run at 266.14MB/s.

The 20TB Red Pro's peak read result of 287MB/s is the fastest for an HDD we’ve seen to date when it comes to read throughput.

The WD Red Pro's write performance isn't as good as the read, peaking at 278.30MB/s.
