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.
The official 4K random performance figures for the drive are up to 95,000 IOPS for reads and up to 90,000 IOPS for writes. In our 4K random tests we could confirm that read figure with the review drive producing 95,343 IOPS. When it came to random 4K writes we couldn't quite get to that maximum figure, the drive producing 85,901 IOPS.
