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.
When it came to Random 4K performance we were able to beat the official figure for reads of 95,000 IOPS, the tested drive producing 99,261 IOPS. Write performance, however, was a little shy of the official 90,000 IOPS at 88,158 IOPS.
