IOMeter is another open-source synthetic benchmarking tool which is able to simulate the various loads placed on a hard drive and solid-state drive technology.
We set IOmeter up (as shown above) to test both backup and restore performance on a 100GB file.
WD's Black D50 Game Dock handled our backup/restore test with ease, with an 887.88MB/s bandwidth score for the backup test and 506.82MB/s for the restore test.
