The PCMCIA bus.

Fast CF cards can only achieve the higher performance levels when
operating in 
"True IDE" mode, connected to an IDE controller that supports the faster
modes.  In PCMCIA compatibility mode, 2 MB/sec is as good as it's going
to get,
and that's actually pretty good compared to most PC based PCMCIA
