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.
In our 4K random read/write test, the drive produced a write figure of 661 IOPS, which is slower than some other capacities of the IronWolf Pro we've tested. However, its read result of 784 IOPS is one of the fastest we've seen to date for an HDD.
