Futuremark PCMark 7

PCMark 7 incorporates an individual disk subsystem benchmark which is based on real-life applications. It reproduces typical disk usage patterns and measures how fast they are performed. Moreover, the disk access commands are not reproduced one by one, but with pauses necessary to process the data, just like in real life.

The benchmark reports an overall disk subsystem performance rating as well as the data-transfer rate in particular scenarios. Take note that the speed in these scenarios is rather low due to the pauses between input and output operations. In other words, PCMark 7 shows you the speed of the disk subsystem from the application’s point of view. Rather than the pure performance of the SSDs, this benchmark will show us how good they are in practical tasks.

The PCMark 7 scores separate the SandForce-based SSDs into faster (with synchronous flash) and slower (with asynchronous flash) products. The Corsair Force GT belongs to the former group whereas the more affordable Force 3, to the latter. Based on a different controller, the Crucial m4 takes an in-between position.

The difference between the Force GT and Force 3 is no larger than 9%, which is not much but reflects the real situation truthfully enough. That’s the advantage you should count on if you prefer the Force GT to the Force 3.

You may want to take a look at the individual subtests. The gaps between the SSDs are quite impressive in some of them.
