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 Hard 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 extra cache in the X300 gives it an advantage over the P300 in the IOMeter 4K random write test but the real advantage of the larger buffer can be seen in the random read test.
