The SanDisk Extreme FireWire CompactFlash Card Reader is a high performance CF card reader. It offers the highest transfer speed and performance with a transfer rate of up to 40MB/second with sequential read and write.
It has one slot for CF cards only. No other cards are supported.
It supports FireWire 800/400* connectivity on both Windows and Macintosh Operating Systems, and draws power directly from the FireWire interface with no external AC power. FireWire is also known by other names, including IEEE-1394, i.LINK, and Lynx—however, it is not the same thing as USB, so if all you have is USB, this won’t work.
