I have hundreds of gigabytes of movies/songs, etc.. which I've bought online over the years. Since now we're seeing predictions of internet outages for weeks at a time due to "extremists", and since we're seeing general instability, I was thinking I'd like to download all of the stuff for my family to local storage that doesn't require internet to watch. 6 or so years ago I bought a storage device that was like a bluetooth san device. It was one of the first of its kind but only held 25gb or so. OBVIOUSLY technology has advanced quite a bit. Usually I'm a bit anal about what I buy and I do thorough research in advance but I'm insanely busy so I'm looking for suggestions. I want either wifi/BT remote san, accessible by ipads/iphones and if it's something that I can swap out storage to increase it, and of course also clone as needed, that's even better. Thanks in advance.
