I plan on waiting until 2012 to buy a new MacBook pro since I think they will redesign the shell in 2012. So I want to upgrade and get as much life out of the 17" MacBook pro I have now. I am looking at putting in a 500GB SSD. I know I can do 2 250GB drives, pull out the DVD and RAID them but I would rather not do that. What drive do you recommend?
