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.
Crucial quote random 4K read/write figures for the MX300 TB as up to 92,000 IOPS for reads and 83,000 IOPS for writes. Under test conditions the drive matched the official read figure, producing a score of 92,861 IOPS while the write figure was a little shy at 81,045 IOPS.
