I am looking for a 500 gig drive for my mbp and i rely wanted to go with an ssd. I have seen 512Gig ssds and am wondering if anyone has found one to buy or a release date for them. I know 250gigs have gotten much cheeper so i looked into this http://www.mcetech.com/optibay/ to use 2 X 250 gig ssds. Dose anyone know if installing this voids your warranty. It seems like it would and their site doesn't say anything about it. I found it interesting that the bracket alone costs twice the price of most 500gig hdds. Also anyone using and ssd rely finde it better?
