I think it would be pretty slow - my CF cards seem to give only
5-6MB/sec transfer. Even my slowest hard drives run a LOT faster than that.
There is something strange with compact flash on IDE on linux. I've
seen speed problems with several brands, but I'm going to talk
specifically about kingston since I have detailed data sheets for their
CF cards. Standard cards get about 5MB/sec write speed. This is about
what speed they are supposed to get. However, when I upgrade to "100x"
cards, my speed actually starts going down and there are kernel errors
printed about accessing the flash. According to Kingston data sheets,
these "100x" cards should be getting about 16MB/sec writes, which is
vaguely in the ball park of IDE, and plenty adequate for most audio
work.
I use a 50x CF from Kingston without any problems, but I don't write to
it from my computer. I only use the computer to read photos from it.
