I have a 17" Mid-2010 MBP. It's currently got a WD 2.5TB powered USB 2 drive attached with all my content. It's connected to my network via 802.11 5Ghz running in 40Mhz/'n' mode only. I have an ATV 3rd gen connected via 100mbps Ethernet. Would I see any performance gain in replacing the USB2 drive with a Firewire 800 one?
