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 use a custom Kitguru configuration for 4k random write to measure performance.
There are many different ways to measure IOPS performance, but with our own custom script, this particular drive scores 23,840 IOPS, which is significantly lower than many Sandforce 2281 powered drives we have reviewed in recent weeks.
