Ok, so I'm a radio dj and as you can imagine i have loadddssss of music. And music isn't kind when it comes to space...especially when you have 2 months worth. I have a Macbook Pro 15" Unibody from April 2009. It has a 2.66 GHz Intel Core 2 Duo Processor, and 4GB 1067 MHz DDR3 Ram Memory. I currently house a 320GB Hard drive. I have searched everywhere, including this forum up and down before I came here to ask, so here I am. Where can I get a new, larger hard drive? Such as 750GB or even a terabyte? Any assistance would be much appreciated! Thanks everybody!
