IOGEARs FireWire hubs provide IEEE 1394a compliant ports that support data transfer rates of 100, 200 and 400 Mbps (megabits per second), and automatically switches to the highest speed that the peripheral supports. FireWire peripherals connect up externally; simply by plugging in cables. Configuration is automatic - there is no need to specify memory addresses, IRQ assignments, device IDs or to plug in terminators. IEEE 1394-compliant peripherals can be hot swapped (added and removed without having to shut the computer down). The fastest growing use of FireWire is in the realm of digital video (DV) devices.
