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.
The OCZ Vector 150 drives performed very well in the PCMark storage benchmark. Note that the 120GB Vector 150 has no trouble competing with higher capacity drives here, and the 240GB drive comes within a couple of percentage points of the leaders.
