I'm currently using Aperture with a local library on my Mac using referenced images on my Sinology NAS. I'm interested in Photos.app, but I'm not ready to completely trust cloud services, and I don't have enough local storage for all of my photos. I know I can work with reference images in Photos.app, but it's not as easy as it was in Aperture to import and move as reference, and it seems I'd have to copy the images externally using Finder or Image Capture, THEN import them into Photos as reference images. I saw this article about using NFS with FCPX libraries, and was able to set up a NFS share on my Synology NAS. I know there are potential issues using a Photo library over AFP or SMB and it is recommended against it. I'm not a networking expert, but does NFS handle complex databases and lots of files better than the other protocols? Am I asking for trouble using a NFS share for photo storage?
