Magma EB3T-DB overview

  • 1Description

The EB3T-DB ExpressBox 3T 3-Slot Thunderbolt 2 to PCIe Expansion Chassis from Magma contains three PCIe slots that connect to a computer through a Thunderbolt cable. It allows you to attach three full length PCIe cards to your Thunderbolt 2 equipped computer, and turns your computer to an audio/video editing workstation or a scientific workstation. The expansion chassis supports high performance workflows, when a Thunderbolt equipped computer is connected to it with PCIe cards for video capture, media transcoding, audio processing, and fast data storage. Since the Thunderbolt is also based on DisplayPort technology, you can daisy-chain a high-resolution display with the expansion chassis.
