I recently bought a late 2011 17 MBP It has 4gb of memory I am putting 16gb in it. It has the 750gb standard drive it. I think that needs to be swapped out. The people that have upgraded did you notice performance increase? How bout the heat? Are you doing dual drives SSD and the standard in replacement of the super drive? Did you go with standard SSD or hybrid? I do run a couple virtual pc's on the MBP and they run like crap right now I am sure from the low memory. So I would like to say around the same size drive I guess. So is it worth the money to upgrade?
