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.
Samsung’s random read figure for the 860EVO is up to 98,000 IOPS with write performance quoted as up to 90,000 IOPS. The review drive hit the read figure on the nail with a score of 98,907 IOPS. The tested write performance fell a little short of the maximum official figure at 84,761 IOPS.
