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 comes to random 4K performance, the official figures for the 512GB SC311 are up to 100,000 IOPS for reads and 90,000 IOPS for writes. Using our 4K IOMeter tests we couldn't match that top figure for either but with reads of 98,972 IOPS and 82,189 IOPS for writes, the review drive was still well in the ball park for both.
