Tl;Dr: Any downsides to just hooking an external HD up to an airport extreme? I have a 500GB HD that I use for pic/music backups (enough storage) but my other HD I keep a backup of everything on is about 5 years old and won't connect sometimes and will sometimes randomly shut off. It's 5 years old, survived college, and HDs fail, so I'm looking to buy a 1TB for everything, keep the 500GB for music/pics still. My music/pics are the one thing that if I lose, it'll really, really suck. Everything else would be cumbersome but not terrible (especially since banking stuff is online). So, I was thinking of either going TC or Extreme+external. I don't see a downside to the Extreme+external, other than it's not as sleek and they're separate, and I save money. Am I missing anything here?
