USB 3.0, kind of pointless right now.
k, i read that external hdd transfers can be slow so i wanted to make sure and give it the most bandwidth i could.
the whole reason why i am dealing with this is because my router (airport extreme) has decided to only assign one IP address at a time. so i can't hit the internet with more than one device at a time. on the 2nd device, i'll get a "Self-Assigned IP Address"
