I have a 500GB FreeAgent external HD with FireWire. I love it; it's been great. http://www.tigerdirect.com/applicat...&cm_mmc_o=TBBTkwCjCVyBpAgf mwzygtCjCVRqCjCVRq I'm thinking of buying another. I notice the USB one, without the FireWire option is significantly cheaper. Isn't FireWire better though? More reliable? Would you use USB for this purpose? Thanks so much for any replies.
