No firmware, software or driver is required from Magma, but you may need an updated driver for your PCIe card.
Maximum PCIe card length for ExpressBox 1T is 7.75" long. Check the PCIe Card Compatibility Page for a list of cards that have compatible drivers. If your PCIe card is not on this list, contact the card manufacturer to ask if they have a Thunderbolt Compatible driver.
No, it will not work as a add-in PCIe card in a Mac Tower.
"The Magma ExpressBox 1T is, in my opinion, a very high quality expansion chassis. It is an excellent match for the Lynx AES16e series of PCI Express cards, allowing them to access the Thunderbolt bus on Apple computers. The ExpressBox 1T’s compact size and rugged construction make it ideal for our purposes.
Installation was a breeze. I just opened up the chassis, slipped in the AES16e, closed the chassis and plugged in to the Thunderbolt cable. Once I installed the Lynx driver, I was up and running. Magma was also very responsive to our request for a variable speed cooling fan. As our cards do not require a lot of cooling, a low speed on the fan allows quieter operation in a studio. This is a very high quality product and a great value as well."
- David Hoatson, Co-Founder and Chief Software Engineer, Lynx Studio Technology, Inc.
"We've been using the ExpressBox 1T with our Symphony 64 PCIe card for several weeks now, and QA has given it the thumbs-up for its high performance and smooth user experience."
- Roger Robindore, Director of Product Evangelism, Apogee Electronics
"Thunderbolt technology combines high-speed data and display transfers, delivering great responsiveness with absolute ease of use. Magma’s upcoming products will use Thunderbolt technology to extend system capabilities even further."
- Jason Ziller, Director of Thunderbolt Marketing, Intel
