WD Red Pro 22TB HDD Review

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 test with both random read and write 4K tests, as shown above. There are many ways to measure the IOPS performance of a hard drive, so our results will sometimes differ from the manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.

The 22TB Red Pro's 4K random write result of 810 IOPS sees it into the top 5 HDD drives we've tested to date. Its random read figure isn't quite as impressive though, at 722 IOPs.
