We like PCMark's Storage 2.0 benchmark module for its real-world application measurement approach to testing. PCMark
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 and photo editing with Adobe
applications, we are 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 trace-based PCMark tests are a good indicator of Intel's consumer workload-oriented optimizations with the 660p. Peak transfer rates may not match some of the more expensive drives, but with actual application workloads the 660p finishes near the top of the charts and trails only the Samsung drive.
