Product Description

High-Speed, High-Bandwidth Ports for Fast Data Transfers

Camcorder connected to Allegro FW800Do you work with files stored on external hard drives? You may not be getting the maximum performance from them. Many drive enclosures feature a FireWire 800 (1394b) interface, which provides up to twice the data transfer speeds and bandwidth of FireWire 400 (1394a), both critical attributes when working with multimedia applications. Don’t settle for a slower connection and less than maximum performance; get a Sonnet Allegro™ FW800 FireWire 800 adapter card to take advantage of the extra speed FireWire 800 offers!
