I am considering moving to a rMBP from a mid 2010 3.33 Ghz MacPro 6-core with 12GB ram. A couple questions... First and foremost, what will the difference in performance be? I use my mac primarily for video and photo editing, so a lot of fcp7, photoshop cs6, apple color. Second, what's the best way to handle my data... I am interested in the laptop because of increasing time away from home and therefore my main work computer, but I am not sophisticated about data management since it is so simple on the desktop with multiple internal HDDs and automated backups. My home folder is currently 1.5TB full. Most of that is video and photos, and then a lot of music too. For the sake of argument, let's say I need it all with me, and the ability to back it up continuously... What is the best way of going about that? 2 2TB externals? How does it work with the externals for something like an iPhoto library or iTunes... can those be directed to find their libraries on different disks than they reside? Lastly, is it possible to essentially sync whatever storage I have with the MBP with the existing MacPro while I am on the road? Like a private cloud situation basically. Any help would be appreciated tremendously! Thanks in advance.
