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 often vary between the manufacturer’s quoted ratings.
The SK hynix SH920/910A scores well in the IOPS 4k random test, and our results are actually very close to the official company claims (94k random read/71k random write). Minor variables are related to different testing methodologies.
