Sonnet"s Tango Express features three USB 2.0 and two FireWire 400 ports, each independently powered and capable of supporting bus-powered peripherals (devices that can work without a separate power supply, including some external drives and scanners). And unlike hubs, each port offers full-bandwidth data throughput, so there is no performance penalty due to two or more devices sharing a single connection. Best of all, Tango Express offers simple plug and play installation you"ll be more connected in minutes.
