| What's the difference between the Allegro FireWire 400 Express, #FW400-E; and Allegro FireWire 400 PCIe, #FW400A-E ? | Aug-19-09 | | #FW400-E (now obsolete) had two external ports. #FW400A-E (current version) has three external ports. #FW400A-E also uses a higher performance FireWire controller, which translates into higher bandwidth to storage devices. | |
