I have a Mac Mini with a 120 SSD for OS and Apps, and the 500 GB that it came with as a Scratch disk. My Aperture Library consisting of mostly family snapshots and video has ballooned beyond 500 GB. I use a managed library approach to take advantage of the vault backup. In an effort to minimize the attached storage I had decided to create a separate Aperture Library for 2014 and I'm considering transitioning the old library to a Synology NAS, possibly retroactively breaking it up into separate year libraries with a running "Best Of" library containing selects from all collective years. I have a few reservations about this set up. NAS storage may not be fast enough. I figured this would be good enough for the occasional review of older libraries, as editing would occur mostly on current images on scratch disk. Multiple libraries could be a headache and result in duplicates. My wife takes photos and imports them as well. Depending on which library is selected at start up, she may import images into the wrong library. I also ran into a problem when I needed to unload photos from her iPhone to clear space. My new library did not recognize all the old photos as duplicates, making importing and managing the iOS devices more difficult. I'd be curious to here how others are managing their libraries as we become more mobile and SSD's have shrunk storage sizes. How do preview images play into this scenario? That's something I haven't really looked into. Now that I have other backup solutions, referenced images may be an option. Not to get into a Aperture vs. Lightroom debate, but would cataloging in LR be any different on network storage? Is anyone using the Synology Picture Station? Thanks for your help!
