I am at a complete loss as to what one do for fun and profit with that much storage after backups/work and audio media is accounted for. But here is this: http://atp.fm/episodes/22-full-brichter It's a podcast (called Accidental Tech Podcast) from some well known Apple devs (creator of Instapaper, back-end for Tumblr, and some other stuff) and writers. Topics vary, but in this one they basically geek out and do some lengthy coffee-talk about NAS options. If memory serves, this was also the first episode after Synology heard them geeking a bit on NAS a couple episodes before, and shipped at least one of them a unit to have out of the blue. They used it and ended up giving their first impressions on this podcast. Anyway, it sounds like this episode they are speaking from a similar place you're in now regarding your Synology gear, unless you've used their stuff for a while.
