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 AMD Radeon R7 Series 240GB SSD performed extremely well up to this point, but the trace-based tests in the PCMark 7 storage benchmark didn't paint the drive in such a good light. Here, the AMD Radeon R7 Series 240GB SSD trailed all of the other drives, save for the ARC 100. We should point out, however, that it's only the "Starting Application" tests that drags the score down. The others were much more competitive.
