What's the fastest copying setup for a Mac with two USB2.0 and one FW400 ports? The data is to be transferred involves two external drives, both with USB2.0 and FW400 ports. The amount of data transferred is in the order of 300 gigabytes. a. Both drives connected via separate USB ports b. Read drive on USB, write drive on FW c. Read drive on FW, write drive on USB d. Daisy chain BOTH drives on FW400 Wish I can simply swap the HDDs inside the drives over but this is not an option.
