I believe the F3 raid would be better option I got one of them and get read speeds of 146mbs which I belive is very close to the cheap ssd's so two of them should beat it unless your getting a more expensive sdd like the corsair one or samsung![]()
The seek times of moving the head of the hard drive across the platter is nil with SSD as there isn't one. This makes loading small files very fast, so an SSD will always out-perform a mechanical drive for loading the OS every time.
