This was modded funny, but for popular data, this is essentially what I would recommend. Why spend a fortune on big hard drives, enclosures, power supplies and all that for stuff that can be tracked down and downloaded easily? Sure, storage is cheap, but you're still talking a few hundred here. Personally, I have a decent sized drive that I store stuff until I watch it, then I just delete it. I never back the thing up and consider it's contents completely disposable. If I really want to have a permanent copy of a movie I just buy the damn thing. I do keep a mirror or two of my music collection though. But at less than 200GB it's a little easier to maintain.
