I do apologise if this has been asked before. I did have a quick search around but couldn't find an identical question.

I have a Macbook pro 15", bought in Oct 2009 and Im just looking to upgrade the 500gb harddrive to 1TB.
Im weighing up two drives at the moment. The WD Scorpio Blue and the Samsung Spinpoint.

Or alternatively I think I could opt for the WD Scorpio Black 750GB as I do a lot of photography editing and movie converting...?

I just wanted to know if these are suitable and will actually fit and/or are there any others options that would be more suited or better at all?
