Hi all, I have a MacBook Air 128gb connected to my Thunderbolt Display. I have 50gb of photos that I want to start organising in Aperture. I do not want to store these on the Airs internal drive, so I'm looking at keeping the library on the Air, and the masters on an external hdd. I'm considering the LaCie rugged 256gb ssd drive, and plan to keep this permanently connected to the Thunderbolt display. What will happen when I disconnect the air from the display? Will I need to unmount the drive each time? Also, I have little doubt that this drive will be fast enough, but would a higher capacity standard thunderbolt drive be suitable?
