Title says it all. After three years, my Time Capsule is making awful grinding sounds. In doing some searching it would seem the TC has a checkered history and does not really live up to Apple's normal standards, plus they have stopped developing the product. So it seems reasonable to expect whatever causes these things to die early is still unresolved. I could be pragmatic and say "it's only $300, just buy another". But it seems to me it's time to look elsewhere for a wifi/backup solution. Question (finally!): What are the options?
