Currently I have a Time Capsule and a connected USB drive (to the Time Capsule) to backup all of the macs in my house. Problem is the USB connected drive is sooooo slow so I was thinking of changing it for another Time Capsule. Can I add a 2nd Time Capsule to the ethernet port of the first and then chose which one to back up to just like I can with the setup I have now? Connection to the Time Capsule is currently by ethernet so the wifi part is of no interest to me. My other option is to simple replace the single 1TB Time Capsule with a 2TB.
