Some adapters do DMA and some don't. You want DMA (costs no more).
Some CF cards do DMA and some don't. You probably want DMA (may cost
Some CF cards have SLC (single-level cells) and some have MLC

Mark Lord gave a nice presentation at the Linux Symposium about using
a RAM disk to speed up this kind of setup. During his talk, I
actually dropped his scripts onto my notebook running Ubuntu 9.04.
They worked with no tweeking (except for adding a grub entry).
