I'm also using an IDE-flash adapter with a 512 Mb compact flash. I put
a debian on it, customize it a lot to avoid all writting during boot
process and runtime (to extends CF life time). / is mounted as read
only, /tmp and /var are in a tmpfs. I'm very happy with it as it makes
no noise and small. Perfect for a htpc :)
The drawback is that I can't enable DMA on it, my CF doesn't support
it. It may be little slower than a "normal" hard drive but it doesn't
matter. I don't know if a newer one will supports it.
