My old firewire drive is dead. I have a G4 dual with usb 1 and Firewire 400. I could get a firewire drive for $200 or for the same price buy a usb 2 drive (same size) and a 4 usb 2 card to install in my Mac. Is there any disadvantage of going the usb 2 route? It seems that way I could use the drive when I go visit my son who has a pc. Is it a simple plug and play (no software) for the usb card (I was looking at a store brand card at CompUSA.
