Use the enclosure's two Thunderbolt 2 technology ports for:
Thunderbolt 2 technology is an update of Thunderbolt technology. While Thunderbolt technology continues to provide impressive transfer rates of up to 10Gb/s bi-directional, Thunderbolt 2 technology offers improved performance with a potential of up to 20Gb/s bi-directional. Thunderbolt 2 technology also gives you greater flexibility when using video and data, assigning greater throughput to the stream that carries the heavier load. You must have a computer that supports Thunderbolt 2 technology in order to take advantage of the updates in perfomance and the intelligent sharing of bandwidth.
Similar to first generation Thunderbolt technology, a single Thunderbolt 2 technology daisy chain can have up to seven devices, including the computer. For example, you can daisy chain five Little Big Disk Thunderbolt 2 enclosures on the same line with a display. Provided that your computer supports Thunderbolt 2 technology, transfer rates have the potential to reach up to 20Gb/s bi-directional for all devices.
You can also add the Little Big Disk Thunderbolt 2 to a daisy chain that includes first generation Thunderbolt technology devices. For example, your computer supports Thunderbolt 2 technology and you add the Little Big Disk Thunderbolt 2 to a daisy chain that includes three first generation Thunderbolt technology storage devices and a display with a MiniDisplay port. In such a case, make certain that the Little Big Disk Thunderbolt 2 is the first enclosure connected to the computer. You can lose the higher performance offered by Thunderbolt 2 technology if the Little Big Disk Thunderbolt 2 is daisy-chained behind first generation Thunderbolt devices and/or displays.
Connect the cable to one of the interface ports on the back of the Little Big Disk Thunderbolt 2 and to your computer. The additional port may be used to daisy chain compatible first generation Thunderbolt and Thunderbolt 2 peripherals, such as hard drives, monitors, and much more. If you have another Thunderbolt 2 storage device, make certain to connect it to the Little Big Disk Thunderbolt 2 before adding first generation Thunderbolt technology devices and/or displays.
