Any ideas on a good NAS for a mostly Mac network? Right now we currently use a Western Digital 1TB that is connected to an Airport Extreme, but I know there are better solutions out there. We don't want to get rid of the Extreme, but something to just plug into the Ethernet port of the extreme for maybe a little bit faster transfer time. (If only Apple had placed a Firewire port instead of a USB port in the Extreme ). Maybe a Time Capsule, or maybe a Buffalo NAS?
