I was at Best Buy the other day looking for another external HD. I told the employee in that area that I need an external HD with Firewire. After we looked at some different models he told me that USB 2.0 if faster than Firewire. "What!?!" He said that "Firewire is only better because it doesn't loose speed with length. USB 2.0 does. So if I'm using a short cable, USB 2.0 is faster." We never specified whether he was talking about 400 or 800 (which I wish I would have.) I was just too shocked that the tiny USB cord is faster than my sweet Firewire cord. And also how much cheaper USB is over Firewire. I did go with the USB 2.0, but can't tell any difference compared to my Firewire external HD. (the new Seagate 320gb USB 2.0 compared to my Lacie 300gb Firewire 400) Was he crazy or correct? Was I an idiot for believing him?
