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 are using a custom 4k sequential read test today to measure IOPS performance.
The drive returned an IOPS score of almost 73,000 which is very positive. OCZ claim up to 120,000 IOPS with a 4k random write test, but we only managed to get around 88,000 with our own settings as we aren't aware of how OCZ achieved their claimed figures. Still, it is more than capable.
