IOMeter is another open-source synthetic benchmarking tool which is able to simulate the various loads placed on a 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 the manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.
The 960GB Kioxia Exceria is rated as up to 81,000 IOPS for 4K random reads and up to 88,000 IOPS for random writes. While we could confirm the read figure with our four threading testing result of 81,661 IOPS, our random write result figure of 65,831 IOPS was well short of the official maximum.
