USB 3.0 will replace Firewire IEEE 1394

USB 3.0 Specifications are finalized by the USB promoter group. The new interface gives ten times higher speeds than its predecessor USB 2.0 and is expected to be incorporated into future computer peripherals and consumer devices. Of course, even if the hardware manufacturers immediately adopt the new technology, we do not expect new products to incorporate the new standard soon.

The announcement of the USB promoter group follows the decision taken by Apple to abandon the Firewire technology, at least in some of its systems, knowing that USB 3.0 will exceed the bandwidth of Firewire (IEEE1394).

The main features of the new USB 3.0 technology include:

  • 5 Gbps transfer speed
  • Fast Sync-N-Go
  • Download 27 GB High Definition Movie in 60-70 sec
  • Optimized Power Efficiency
  • No device polling
  • Lower power requirements
  • Backward compatible with USB 2.0

Comparing the new USB 3.0 standard with the older one (2.0), we get ten times more speed (5 Gbps compared with 480 Mbps). Even though IEEE announced the new IEEE 1394-2008 specification, which increases the interface bandwidth of IEEE1394, also known as Firewire, to 3.2 Gb/s, major industry players such as Apple seem to have lost interest to Firewire.
