Transcend SSD220S 480GB SSD review

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.

IOMeter setup

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 manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.

Transcend quote 4K IOPS performance figures for the SSD220S 480GB at up to 80,000 IOPS for both read and writes. Unfortunately the review drive failed to get anywhere near that figure for either. For reads the drive produced an IOPS figure of  71,121 IOPS while writes were a very disappointing 21,145 IOPS.
