IOMeter is another open source synthetic benchmarking tool which is able to simulate the various loads placed on 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 manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.
The 4K random read/write IOMeter test finds the Toshiba P300 sandwiched between the two WD 4TB drives. Both its read and write performance is considerably quicker than the 4TB WD Black although both figures fall short of WD's Red drive performance.
