Results: PCMark 7 And Trace
The 840 Pro’s performance is a bit higher attached to the 6 Gb/s port compared to the 3 Gb/s connection under PCMark 7, though the difference is small.
The overview shows that loading applications and importing pictures in Windows Photo Gallery happens faster over a SATA 6Gb/s port than a 3 Gb/s connection. Of course, even then, the throughput-constrained SSD is still way faster than a hard drive.
Our gaming trade only favors the 6 Gb/s port by a bit.
