Futuremark PCMark 7

PCMark 7 incorporates an individual disk subsystem benchmark which is based on real-life applications. PCMark 7 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 ratings separate the expensive SSDs with synchronous memory from the cheaper ones with asynchronous MLC NAND flash. The OCZ Vertex 3 Max IOPS is the best of the high-performance products while the OCZ Agility 3 and Patriot Pyro, among the affordable ones.

On the other hand, we can see that the fastest and slowest SSDs differ by less than 10%, which reflects their real-life performance. You may want to take a look at the individual test scenarios to get a full picture.
