I'm using up ALOT of hard drive very fast with my Logic recordings. I'm thinking of maybe getting the maximum 750GB Drive but I'm not sure. I'll also probably need to get RAM. It 'freezes up', crashes(?) with my 3GB of RAM fairly often. I'm thinking of springing for 2x2GB sticks for a total of 7GB RAM but not sure I need all that either. Does anyone have any suggestions on which and where to buy..?
