I have a 2012 mac mini that i use as a desktop. I just bought a macbook pro and am now looking at ways to maintain files across systems. I currently use plex media server on the mac mini. I also have a large itunes library. I am also graphic designer so I have 1TB worth of workfiles as well. I want to set up a NAS to share all of these files. I don't plan on running plex on the synology so transcoding would be done on the mac mini for video files. I also plan on using the NAS for backing up the laptop, mac mini and all media files. With this said, is there any real reason to choose the synology DS415play over the DS414j? How big of a deal will the lower system memory and cpu frequency matter since I won't be transcoding video? Is there anything I should consider relating to the itunes server and full backup needs? I am trying to find the most cost effective solution since I just bought the macbook pro but at the same time I want to make sure I get everything I need. Thanks in advance.
