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 overall PCMark 7 score can serve as an intuitive benchmark for users who want to know the relative standings of SSDs in terms of performance but do not care about learning the technical details. PCMark 7 sorts the SSDs out in three categories: 1) fast ones with the SF-2281 controller (that’s where the ADATA S511 belongs); 2) slow ones with the SF-2281 controller; 3) average SSDs which are represented by the Crucial m4 with its Marvell controller.
You may want to take a look at the individual subtests. The gaps between the SSDs are quite impressive in some of them.
