This Thunderbolt™ cable is 6 ft. long. It features a Thunderbolt™ connector on both ends of the cable.
It allows you to connect Apple products (and other products) that support Thunderbolt™ technology.
Thunderbolt™ technology is currently the fastest way to transmit data between equipment that supports the technology.
For instance, it is the fastest way to transmit data between Mac Products that support the technology and some third party manufacturers - currently, third party manufacturers are incorporating the technology on portable hard drives, so backing up your data to a portable hard-drive saves you a lot of time.
