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 128KB Sequential read and write tests as well as random read and write 4K tests, as shown below. 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 test setups we use are listed below. Each is run five times.
128KB Sequential Read / Write.
