Thunderbolt became more than just a Mini DisplayPort with potential this morning. The iMac and MacBook Pro both received Thunderbolt-related software updates yesterday, and this morning the Apple store has added the first Thunderbolt cable, as well as the first Thunderbolt peripheral in the form of the Promise Pegasus R6 external RAID array.
The cable costs $49 and works for both data and display connections. The RAID drive is a bigger commitment, starting at $1,499 for the 6TB model. Apple has previously mentioned eight Thunderbolt devices, ranging from external storage to video capture hubs, but as of this morning, the Pegasus drive is the only Thunderbolt peripheral currently available for purchase.
