I'm about to put in an SSD in my 2008 penryn MBP 4.1. Right now I'm thinking about the vertex 2 or the intel 510. I know my computer won't fully be able to use the intel 510, but will it work at all with sata 3? Is that backwards compatible with my now three years old MBP? If I buy that one I can use it in my next computer after this one dies. Otherwise I think I'll go with the vertex 2 (seems to be faster than the X25-m after some googling around) Sorry if this has been answered, I'm either a lousy forum searcher or blind. Thanks a bundle!
