Of course, especially read performance. But if you think you can saturate SATA 2 link speeds you'r ...
I did not expect to saturate the SATA, and it is still a very nice step up from SD
I use more powerful boxes when I need the bandwidth - my video editing box has an SSD for OS/boot, and four striped 7200rpm 1TB SATA3 drives for the video files.
That box (3.8GHz eight core AMD) has ridiculously fast read/write bandwidth for large contiguous files, as I recall testing showed somewhere around ~800MB/sec (far more than needed for uncompressed 1080p) .. I split the array across two SATA3 controllers on different PCIe lanes.
