Looking to upgrade my 13" MBP Aluminum Unibody. Mid 2010. It's only a few months old, but have slowly realized I am burning up the space. I currently have the stock 250gb's. I'd like to go 750, or even 1TB if I can, but not sure about height, or even speed of drives to get the best options. Can anyone here give me a run down on what some options may be for this upgrade? I've been googling for days, and seem to find alot of jargon on different stuff, but want to find out from people who are in the "know".
