After doing that Hanselminutes on network attached storage, Synology, and Windows Home Server, I figured I'd also talk about how we store our original media, in case folks were wondering.
As of this writing, we have somewhere close to 1000 individual DVD discs in various forms - single or multi-disc movies, multi-disc TV sets, etc. - and about as many CDs. Not all of the DVDs are on my Synology DS1010+ - I didn't rip the "special features" discs, and in some cases where I have multiple editions of the same movie, I only ripped the one we like the most....
