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 quoted 4K random read/write figures for the drive are up to 80,000 IOPS for reads and 90,000 for writes and although the review drive didn't quite make those figures when tested, with reads coming in at 71,454 IOPS.

However, the write score of 88,468 IOPS is the fastest we have seen for a consumer 2.5in drive in this capacity segment.
