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 Solid State 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.
Despite carrying Kingston's HyperX performance branding, the 4K random read/write performance of the drive isn't really that impressive, the review drive producing 75,960 IOPS for reads and 54,126 IOPS for writes in our 4K performance tests.
