The StarTech PEX1394B3LP FireWire Card Adapter comes equipped with a low-profile bracket so you can install it in small form factor PCs. It also includes an optional full-size bracket for installation in a standard-size PC case. The three-port PCI Express FireWire card can be installed in a PCIe slot to add two IEEE1394b (FireWire 800 - nine-pin) ports and one IEEE1394a (FireWire 400 - six-pin) port. It has an internal power connector that lets you use high-powered FireWire devices. This PCI FireWire card makes your computer work with various FireWire devices like DV camcorders, external hard drives and digital cameras. The 2x FireWire 800 and 1x FireWire 400 card features a native (single chip) PCI Express chipset. This chipset offers faster, more reliable and cost-effective performance than expansion cards that use a "bridge" chip. This low-profile FireWire card adapter is hot swappable and allows you to connect and disconnect devices without turning off your system.
