All, I have a new 11" MBA replacing an old 2010 MBP that has an SSD in it. I bought an external drive with USB 3.0 as well as a new AC router. My question is which transfer method would be faster? Backup the 2010 to the external (at USB 2 speeds) and then use that as the USB 3 drive for the MBA setup assistant. Or plug the MBP to the router with a gigabit cable and setup the MBA with the AC router wifi speed. Again, the MBP has an SSD, so I'm wondering if the speed of that "disk" as well as the AC router would be faster than the transfer and re-transfer of the files to an external drive. Thanks!
