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.
Officially Samsung quotes maximum 4K read/write performance figures for the 4TB SSD 870 QVO as up to 98,000 IOPS and 88,000 IOPS respectively. In our 4K random tests, the drive fell a little short of both official figures with reads of 93,266 IOPS and writes at 83.335 IOPS.
