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 story with the PCMark 7 tests can be summed up in one word: third. In the overall score and most of the sub tests, the Barracuda 3TB posted the third-best scores, mostly falling behind the Barracuda XT 3TB and Hitachi Deskstar 3TB. It actually did worse in the Video Editing sub test, posting the second-lowest score, but it did slightly better in the Windows Defender sub test and Windows Media Center test.
