Onzin, verschilt nauwelijks in snelheid, plus minder compatible - elke pc heeft usb en maar zelden firewire.
Als het om de snelheid gaat moet je een externe hdd met e-sata nemen, zijn helaas nog altijd een stuk duurder + je moet een geschikte controller met esata aansluiting hebben.
The signaling rate of USB 2.0 Hi-Speed mode is 480 Mb/s, while the signaling rate of FireWire 400 (IEEE 1394a, the sower, yet more common variant of firewire as of 2007) is 393.216 Mb/s,[9] which would appear to indicate that USB should be slightly faster but reality is far more complicated than that and other design factors can dwarf a relatively small difference in signaling rate. USB requires more host processing power than FireWire due to the need for the host to provide the arbitration and scheduling of transactions. USB transfer rates are theoretically higher than FireWire due to the need for FireWire devices to arbitrate for bus access. A single FireWire device may achieve a transfer rate for FireWire 400 as high as 41 MB/s, while for USB 2.0 the rate can theoretically be 55 MB/s (for a single device). In a multi-device environment FireWire rapidly loses ground to USB: FireWire's mixed speed networks and long connection chains dramatically affect its performance.[citation needed]
The peer-to-peer nature of FireWire requires devices to arbitrate, which means a FireWire bus must wait until a given signal has propagated to all devices on the bus. The more devices on the bus, the lower is its peak performance. Conversely, for USB the maximum timing model is fixed and is limited only by the host-device branch (not the entire network). Furthermore, the host-centric nature of USB allows the host to allocate more bandwidth to high priority devices instead of forcing them to compete for bandwidth as in FireWire.
All of the above indicates that USB 2 should be faster than firewire 400 but tests have generally shown that for mass storage using normal consumer equipment firewire is faster often by a significant margin.
Nog even voor je nagezocht.
Hier nog wat benchmarks op een aantal macs:
