Dan Frankes of Macworld with an excellent piece on Thunderbolt, the new “peripheral-connection technology” that Intel developed and is now part of the MacBook Pro line:
In theory, it’s blazing fast. A Thunderbolt channel can provide up to 10 Gigabits per second (Gbps) of data throughput—and each Thunderbolt port includes two channels. Thunderbolt is also bi-directional, meaning it can transmit and receive data at the same time. Even with estimated real-world performance of around 8Gbps, Thunderbolt is many times faster than FireWire 800 and USB 3.0. It’s also significantly faster than the eSATA connections available on many Windows PCs.
Pretty exciting. USB 3.0 has been in the horizon recently and most people thought Light Peak (the code name for Thunderbolt) was a pipe dream that would never come. It will be interesting to see if USB 3.0 becomes of the HD-DVD of this race. Thunderbolt will take years to become widely developed, but it has potential to be a game changer.
