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 Solid State 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.
When it comes to 4K random performance, Kingston rate the 1TB drive as up to 90,000 IOPS for reads and up to 80,000 IOPS for writes. When tested with our IOMeter 4K random test, the review drive confirmed the official ratings with reads at 91,818 IOPS and writes at 83,555 IOPS
