Hi folks, I'm looking to replace my first-generation Time Capsule (circa 2008) with something new that supports 802.11ac. I'd like to keep the convenience of wireless Time Machine backups, but the most recent Time Capsule is really expensive (~$300) and likely to be discontinued soon. Is there any new non-Apple hardware out there that would do the job for cheaper? For example, an 802.11ac router that I could plug into a wired hard drive? Or perhaps a Wi-Fi enabled hard drive that I could connect to my wi-fi network? And are either of these setups compatible with Time Machine? Thanks!
