For some reason, I had not noticed that 640, 750, and 1TB bare drives were available in 2.5" form factor! The TB drives seem to all be 12.5 mm. I have a new 2010 MBP. The manual does not state a maximum height for the drive (as far as I can see), so I'm asking my MacNN friends whether you've bumped up your newest MBP to one of these larger sizes, and which one you'd recommend from Newegg.
