WD Black 2 Dual-Drive SSD+HDD Hybrid Review
PCMark 7 Storage Benchmarks
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.

In the trace-based PCMark 7 benchmarks, which are a better indicator of real-world performance than the synthetic transfer tests in our opinion, the WD Black 2 is competitive with the standalone SSDs, though it still trails the pack by a few percentage points.
