Apple Thunderbolt Cable
Thunderbolt technology supports blazing-fast data transfer with two independent channels of 10 Gbps each. Use the Apple Thunderbolt cable to connect your Thunderbolt-equipped peripherals to your new iMac or MacBook Pro.
The Apple Thunderbolt cable can also be used for Target Disk Mode between two Macs that support Thunderbolt. And it comes in handy while using a new iMac as a display for a MacBook Pro equipped with Thunderbolt, too.
