IOMeter is another open-source synthetic benchmarking tool that 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.
The WD Black P50 Game Drive had no problems dealing with our backup/restore test producing a backup bandwidth of 1,401MB/s (5,347 IOPS) and 1,191MB/s (4,544 IOPS) for the restore bandwidth at full USB 3.2 Gen 2 x2 speed.
