The mLogic mLink is a Thunderbolt expansion chassis designed to give Macs extra storage, networking options, video capture and more. Explains Gizmodo, "The device connects to any Mac with a thunderbolt port, and allows you to install a half-length PCIe board—an ability missing from Mac Minis and Macbooks. That opens up a whole world of exotic features: RAID storage, high speed networking, video capture, or whatever else you can think of that needs a PCIe card."
The $400 model is available now with a $700 model, designed specifically to grab RAW video from RED cameras, coming soon. Read more here.
