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 4k random read and 4k random write, as shown above.
IOPS performance is fantastic, and these are some of the highest scores yet from a Sandforce 2281 powered SSD. ADATA quote higher figures than these, but every manufacturer uses different setup parameters to achieve their results.
