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 Solid State Drive, so our results will often vary between the manufacturer’s quoted ratings.
IOPS performance is actually very strong – OCZ rate this drive at 75,000 IOPS 4k read and 80,000 IOPS 4k random write. Our results are actually a little higher at 78,276 and 88,206 respectively.
OCZ are focusing on the long term sustained write capabilities of the ARC 100 SSD. They sent over an IOMETER icf file just before launch named ‘precondition_12hr.icf’ which they recommended we include in our tests today. We did test both OCZ ARC 100 240GB and Samsung 840 EVO 1TB drives with these settings and our results were very close to those in the table above. We need to look into this a little further before we include these results in our own SSD reviews from this point onwards however.
