Thunderbolt has been out for about a year now, but most companies are just now rolling products out that take advantage of the new technology. Thunderbolt used with external hard drives will probably be the most common use. Companies like G-Tech and LaCie are both rolling out new drives that use the new interface. Thunderbolt is 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. At the moment it seems LaCie has the 1st drives out for sale.
