I was wondering If you have 4 tb drive access for backups, why you choose to use referenced instead of managed. Im about to move my daughter to Aperture from IPhoto 9 and add two, 2 tb external drives to her iMac one 2 tb for here working Aperture Managed library and the other 2 tb for her Aperture vault. Since the Managed Library dose not add to much of file size. Is there a reason I should look at not doing it this way and doing referenced.
Her current iPhoto library is 238 GB's, so I have to move it off her iMac drive of 320 GB's. So I thought a 2 TB should hold her a few years more.
