Since the introduction of the first Focusrite Saffire interface in 2005, FireWire (Apple’s trade name for IEEE 1394) has been a firm favourite among Focusrite interface users with its high speed and reliability. In particular, FireWire and USB represent a great partnership – by having your audio interface on one type of bus and your hard drives on the other, you get the highest possible performance from your computer audio system, and the fewest problems.
