Hi guys! As I am having some serious issues right now with the 500GB 7200rpm drive that came with my July 2009 MBP, I am considering going the SSD way. I would like to have the same 512Gb-ish storage that I currently have, but as my MBP has the "old" SATA interface, which is "capped" at 300MB/s, it does seem a bit of a waste to me, to get a drive that could deliver 400-500MBs. Instead I consider getting the 750GB Momentus XT (8GB SDD on this one?) What do you guys think?
