Our 1Tb Time Capsule arrived last week. I immediately got home with the unit and opened it up.
Not much inside the box, configured the unit. Then set 2 machines to backup to the unit. Things have been going fine since then.
Speed wise from the ethernet based machine seems okay, from the MacBook Air it tends to vary a bit. It works well enough and hopefully future firmware revisions improve things.
I’ll do another post in a few days time that includes screen grabs from all the options that can be configured as seen from Airport Admin Utility, which I couldn’t find on the net before I purchased.
