• Dual-channel, each 10 Gbps
• Bi-directional, equally fast in both directions
• Dual protocol, PCI Express for hard disks and DisplayPort for monitors
• Daisy-chain-able, supports up to six devices per channel
• Woks with both copper and fiber cabling, fiber allows longer cable runs
• Low latency, very, VERY short delays in transferring signals
• Delivers up to 10 watts of power over copper wiring, but not fiber, to support bus-powered devices. (Though this is not enough for most hard disks)
