No, any 1 TB 2.5" drive will fit. It doesn't have to be from Apple.
Some 1TB drives are 15mm. Too big for a MBP. You'll need 12.5mm.
That is what I thought, the only problem is that this have to be 12.5mm or 9.5mm.
Instead of 1tb drive, I prefer to get 750GB 7200rpm WD Scorpio black.
Just one question, Why 750 instead of 1T? Just curious.
It's 7200rpm vs 5400rpm. It should be a little bit faster.
