We really like PCMark 7's Secondary Storage benchmark module for its pseudo real-world application measurement approach to testing. PCMark 7 offers a trace-based measurement of system response times under various scripted workloads of traditional client / desktop system operation. From simple application start-up performance, to data streaming from a drive in a game engine, and video editing with Windows Movie Maker, we feel more comfortable that these tests reasonably illustrate the performance profile of SSDs in an end-user / consumer PC usage model, more so than a purely synthetic transfer test.
All of the drives featured here performed within a couple of percentage points of one another in the trace-based PCMark 7 benchmarks. Though their margins of victory are relatively small, technically, the Samsung SSD 840 EVO mSATA drive (and its 2.5" counterpart) led the pack overall.
