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 Intel SSD 545s offered the best performance we've seen to date from a SATA-based solid state drive in the PCMark Storage benchmark. If you look at the individual results, it didn't sweep the other drives in every test, but in the tests where it did lead, it was by wide enough margins to give the 545s the overall edge across the board.
