I have a Western Digital 160GB External Hard Drive for sale. I bought it a week and a half ago. It is still brand new in the box and shrink wrapped. I am willing to sell it for ~ $115ish. It is USB 2.0 and you can set it to back up your data at a specified time everyday or you can push a button on it and it will do it. It is 7200rpm. Link
Yea the difference between the newest versions of USB and firewire are almost minimal nowadays. It really doesn't matter anymore.
well if im not mistaken usb 2.0 goes almost the same speed as firewire 400 but firewire 800 is faster by alot than any usb.
Yeah it is fast. I have a different 2.0 ext. drive that I have already filled up...real quick...anyone?
