This 3 Port PCI Express FireWire card comes equipped with a low profile bracket for installation in small form factor PCs and includes an optional full-size bracket for installation in a standard-sized PC case. The FireWire card can be installed in a PCIe slot to add two IEEE1394b (FireWire 800 - 9 pin) ports and one IEEE1394a (FireWire 400 - 6 pin) port providing broad compatibility with a wide range of FireWire devices (e.g. DV camcorders external hard drives digital cameras etc.). The 2x FireWire 800 and 1x FireWire 400 card features a native (single chip) PCI Express chipset which provides faster more reliable and cost-effective performance than expansion cards that utilize a bridge chip.FeaturesTwo 9-pin FireWire 800 ports each with transfer rates up to 800MbpsOne 6-pin FireWire 400 port each with transfer rates up to 400MbpsIncludes full/standard profile installation bracketBuilt with a native PCI Express chipset no bridge chipInternal power connector for high-powered FireWire devicesCompliant with IEEE 1394b and backwards compatible with IEEE 1394a - 2000 as well as 1394-1995 standardsPlug-and-Play and hot-swap compatible
