Hi folks. This is my first post. Just got a new MacBook Pro, and I want to back it up wirelessly using Time Machine over my Airport Extreme Network. I've been doing this, in the past, with a smaller hard drive connected to the USB port on the AEBS, but need to upgrade to a bigger hard drive. Is there any speed benefit from getting a hard drive with ethernet capability, and attaching it right into the ethernet port on the AEBS, and if so can I back up with Time Machine wirelessly using this configuration? My AEBS is the first gen of the 'n' version that came out, but is gigabit ethernet, if that matters. Many Thanks.
