Magma ExpressBox¹ is an easy-to-use external expansion device for attaching a PCI Express® card to a laptop or desktop computer. 

In a mobile environment, ExpressBox¹ allows a user to combine the power of a desktop and the mobility of a laptop into a powerful, flexible, mobile workstation. For example, a user can turn a typical, middle-of-the-road laptop into a powerful gaming computer, a scientific computer, or an audio/video editing workstation simply by adding the right PCI Express card to ExpressBox¹ and then connecting it to a laptop through an ExpressCard/34 module and cable.  

In the desktop computers and servers, ExpressBox¹ allows a user to move full-length, heat-generating, or power hungry PCI Express cards outside the computer by providing dedicated power and cooling in an external enclosure.  ExpressBox1 is ideal for attaching full-length PCI Express cards to low-profile computers that have limited space.  The connection to the host computer is through a PCIe host card and cable.  

Zero latency, 2000Mbps, Faster than USB and Firewire

Based on new PCI Express® technology, ExpressBox¹ provides a zero latency connectivity solution with a theoretical maximum throughput of 2000Mbps (or 250 MegaBytes per second) each direction... That's 2.5 times faster than Firewire 800 and 4.1 times the speed of USB 2.0!
