I've got an iMac Intel Core 2 duo, got a question. I need some feedback on data organization and I'm about to install leopard Right now my data (Music, Video, Documents, Pictures) are on a 300 GB external firewire drive. My iMac has a 250 GB internal hard drive. Would it be best to move all my data (Music, Video, Documents, Pictures) to the internal hard drive and use time machine to back up to the external? Thanks for your help.
