If you’re a video editor, imagine using a single port to connect high-performance storage, a 4K display, and high-bit-rate video capture devices to handle all the post-production for a feature film. Thunderbolt I/O technology allows you to daisy-chain up to six Thunderbolt peripherals, including an Apple Thunderbolt Display and the Promise Pegasus 2 RAID or LaCie 2big disk.* You can even use a Thunderbolt cable to create a fast 10Gb/s link between Mac computers, thanks to IP over Thunderbolt support in OS X.
