Is there anyone here who can advise the best 500GB HD for a 2007 2.33GHz 15.4" MBP? I've got a MBP that's about 4 years old, and it currently has a factory installed Hitachi 5400rpm 120GB HD. It's a great HD, but I'd like a lot more space. I'm looking for a 500GB HD that takes into account the following: Quiet performance at all times, especially when accessing data Low heat Good longevity (if my current HD has lasted so long, I don't see why another one shouldn't be the same) No major drain on battery One of the main things I'd like to take into account is the long-running debate over spindle speed: Is 7200 really better than 5400? If noise, heat and battery drain with 7200 are more obvious than 5400, then I'm not interested. Thank you!
