PCMark7 uses traces based on modern software from the Windows 7 era. This benchmark is the most important one when deciding which SSD to buy, since it uses actual and current applications. A difference with PCMark Vantage is that PCMark7 runs the traces in real-time. Because of this the SSD scores are closer to each other, but the results also correlate better with what you can expect in real-life.
Most of the SSDs we tested score between 4,900 and 5,600 points. The Samsung 840 Pro 256 GB scores the best with 5,591 points, followed by the Plextor M5 Pro (5,451) and various SandForce-based SSDs like the Adata XPG SX900, Corsair Force GT/GS, Kingston HyperX, OCZ Vertex 3 and Intel 520. The OCZ Vector 256GB scores in line with the fast SandForce SSDs. The two Crucial v4s takes last place with 3,600 points, but also the OCZ Petrol 256 GB (4,097 points) and the OCZ Agility 4 (4,681 points) are below-average.
The Windows Defender test is based on a trace in which Windows Defender performs a quick scan of the system.
The importing pictures test is based on a trace in which 68 photos from a USB stick are imported into Windows Live Photo Gallery. The pictures, which have a total size of 434MB, are copied, indexed, and turned into thumbnails.
The video editing test is based on a trace in which an HD video is exported from Windows Live Movie Maker. The film is based on previously imported 1080i MPEG2 videos from a Sony HDR-HC3 camera.
