I am currently on a 2005 iMac but will be moving to a Macbook Pro whenever the new one is released. Will decide at that point if I need the upgrades or just buy a refurb Ivy Bridge. That said I currently have a home network that includes a time machine hung off the iMac and a Drobo too. The Drobo houses iTunes and iPhoto libraries and is slow slow slow much like my entire system. I would like to move to a network that has the new Time Machine Airport Extreme as the router / Time Capsule and then connect the Macbook Pro to a Thunderbolt display. I love the simplicity of the Thunderbolt display and one cable to essentially turn the display into an iMac. My question is, can I hang a 1 TB drive off the Thunderbolt with my libraries on it and when I connect with the macbook the time machine will view the drive and the macbook as one pool of data? Meaning will it back everything up as one, or will I have to partition the drive? Can I even do that?
