Lexar Professional UDMA FireWire® 800 Reader
FireWire 400 is known in the industry as 1394a. FireWire 800 (known as 1394b) is the latest new standard, and offers twice the transfer-rate speed as traditional FireWire 400.
FireWire 800 doubles the throughput of the original FireWire 400 interface with transfer speeds up to 800 Mb/sec.
FireWire 400 devices use a 6-pin or 4-pin connector while FireWire 800 devices use a 9-pin connector. Existing FireWire 400 devices can be plugged into either type of port with the appropriate cable. FireWire 800 devices can achieve FireWire 800 speeds only when connected directly to a FireWire 800 port.
