I have an Apple TV and as of right now, all of my media is residing on my internal HD. I would like to have all of my iTunes media on an external so that I can free up some space on my iMac. So, here's my dilemma... I already use my Fire 800 port for my Time Machine backup drive. So basically that leaves me with either a) getting some type of Firewire hub to support a second Firewire hard drive, or b) just get a USB drive. Any of you guys have to make a similar call? What did you do? If you went with a USB hard drive for your streaming media, how is the performance?
