I haven't up till now thought so much about USB2.0 vs FireWire (which one of them is the best). It has come natural for me, whenever I connect my digital video camera I use FireWire, and I connect my digital "still picture" camera through USB (not 2.0 though).
But now I am thinking about buying a DVD recorder, a Sony DRX510UL (which is an external model). You connect this either through USB2.0 or FireWire.
AFAIK, both standards are quite similar when it comes to speed? What other advantages/disadvantages has one to the other?
