The most portable external expansion device for attaching a single PCIe card to a laptop or workstation as easily as possible

ExpressBox 1

In a mobile environment, ExpressBox 1 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 ExpressBox 1 and then connecting it to a laptop through an ExpressCard/34 module and cable.

ExpressBox 1

In the desktop computers and servers, ExpressBox 1 allows a user to move half-length, heat-generating, or power hungry PCI Express card outside the computer by providing dedicated power and cooling in an external enclosure.  ExpressBox 1 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 PCI Express host card and cable.  


Zero latency, 2000Mb/sec, Faster than USB and Firewire

Based on new PCI Express® technology, ExpressBox 1 provides a zero latency connectivity solution with a theoretical maximum throughput of 2000Mb/sec (or 250 MB/sec) each direction... That's 2.5 times faster than Firewire 800 and 4.1 times the speed of USB 2.0!


Magma ExpressBox 1 weighs only 2.8 pounds and supports single width cards up to 6.604 inches long (EB1H) or 12.83 inches (EB1F).
