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 VX500 series drives did very well in the trace-based PCMark storage benchmark. Though the deltas are relatively small, the 512GB VX500 technically took the lead here, followed by the Samsung drive and then the 1TB VX500. For everyday computing tasks, the VX500 should offer strong performance, especially considering their aggressive price points.
