Sonnet's Allegro FireWire 800 PCIe features the fastest PCI Express to FireWire 800 controller available, the Texas Instruments XIO2213A combined with three full-bandwidth, independently 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.
Customer Reviews of Sonnet 3-port FireWire 800 PCIe Card Adatper - PCI Express - Plug-in Card - 3 Firewire Port(s)
I have a 2008 Mac Pro (3,1) whose FireWire controller died. This Sonnet card works perfectly and installed in minutes. The three ports, each with full bandwidth, are an improvement over the built-in hub. Plus, when I get another Mac Pro, I can move this card over and retain FW ports instead of needing to buy Thunderbolt-FireWire adapters. Definitely a good purchase that I would recommend.
