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 manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.
In our 4K random read/write tests the 14TB N300 was slower than the other two 14TB drives on the chart, Seagate's IronWolf Pro and the Exos X14.
