The technology can be used with any existing peripheral protocols (USB, FireWire, eSATA) via adapters. It can't be upgraded via add-in adapters, however, and you will need to get a new computer or motherboard.
According to Intel, Thunderbolt is designed to co-exist with USB and will slowly change the way users interact with peripheral devices. In the future, the technology can be scaled to support speeds of up to 100Gbps.
