The problem is that I don't know what I want except I want raid 1 and I haven't 
yet found out what the difference is between dmraid and what you call "normal 
software raid". I plan. however, in the near future to install fedora 8 on my 
IDE disks and then play with my sata disks in installing fedora 9 in different 
sorts of raid configurations. I hope that will teach me what the best solution 
will be for me.
