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.
Although the HyperX Predator PCIe SSD drive technically led the pack here, it didn't lead across the board. As we've shown already, small / low queue depth transfers aren't particular exciting with the drive, and as such, overall system performance as measured by PCMark's storage benchmark isn't dramatically affected.
