Futuremark PCMark 7
PCMark 7 contains an individual disk subsystem benchmark. It is not a synthetic test, but is based on real-life applications. This benchmark reproduces typical disk usage scenarios and measures how fast they are completed in popular applications. Moreover, the disk access commands are not executed as a steady uninterrupted flow, but in a more realistic manner – with certain pauses caused by the need to process the data. The benchmark generates an overall disk subsystem performance rating as well as speed readings in MB/s in particular usage scenarios. Note that the absolute speed in these scenarios is not too high because of the above mentioned pauses between individual input/output operations. In other words, PCMark 7 shows you the speed of the disk subsystem from the application’s point of view. Numbers like that show us not only the pure performance of an SSD, but mostly how big of a performance gain a certain SSD can guarantee in real life.
We ran PCMark 7 on “used” SSDs, which is what they are going to be in actual computer systems most of the time. Their performance is in this case affected not only by their controller or flash memory speed but also by the efficiency of their internal algorithms that fight performance degradation.
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. According to this test, the 120GB Zalman F1 delivers average performance and is similar to the Corsair Force GT which, in its turn, is alike to the OCZ Vertex 3 and Kingston HyperX as we know from our earlier tests.
You may want to take a look at the individual subtests. The gaps between the contestants are quite impressive in some of them.
