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

Allegro FW800 PCIe FireWire ports diagramDo 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™ FireWire 800 PCIe adapter to take advantage of the extra speed FireWire 800 offers!

Camcorder connected to Mac and PC with Allegro FW800 PCIe cardSonnet's Allegro FireWire 800 PCIe features the fastest PCI Express to FireWire 800 controller available, the Texas Instruments XIO2213B—combined with three full-bandwidth, powered 9-pin FireWire 800 ports, this card can easily satisfy the high-bandwidth demands of video and pro audio applications. This card also powers bus-powered external drives and audio interfaces, so there is no need to connect an external power brick to them. Offering plug and play simplicity(1), this card works in any PCI Express (PCIe) slot, supports all FireWire 800 and FireWire 400(2) peripherals, and features hot-pluggable and hot-swappable device connection with automatic device configuration.
