Magma's ExpressBox 3T provides an "outside-the-box" solution for using PCIe® cards with Thunderbolt-equipped computers such as Apple's latest versions of the Mac Pro and Mac Book Pro.  High-performance work flows are possible by connecting a Thunderbolt-equipped computer to a Thunderbolt expansion chasis containing PCIe cards such as video capture, media transcoding, audio processing, and fast data storage.  And because Thunderbolt is also based on DisplayPort technology, you can daisy chain a high-resolution display with your Magma ExpressBox 3T.
