FireWire and U.S.B. As Speed Rivals
Question : Which is faster, U.S.B. or FireWire?
Answer : U.S.B. (Universal Serial Bus) and FireWire (also known as
IEEE 1394 and i.Link) each have two varieties, so speed ratings
depend on which versions are being compared. Regular FireWire,
which can transfer data at up to 400 megabits per second, is
faster than U.S.B. 1.1 (12 megabits per second) but rated slower
than U.S.B. 2.0, which can transfer up to 480 megabits of data a
Because of the way each technology controls that data
transfer, however, FireWire is often faster than U.S.B. 2.0 in
tests in copying data at sustained speeds. A faster version of
the standard, FireWire 800, can copy data at speeds up to 800
megabits per second.
