Thunderbolt™ is a state-of-the-art data transfer technology that supports high-performance data devices (RAID, 4K content, etc.) through a single port. Compatible with Thunderbolt 2, perfect for connecting ultra high-resolution displays, IOGEAR's Thunderbolt cables can also daisy chain up to six devices for simplified connectivity. Thunderbolt 2 users can take advantage of transfer speeds of up to 20Gbps, with support for DisplayPort 1.2 displays. Thunderbolt 2 uses the same cables, connectors, and works with existing Thunderbolt devices.
