for a list of supported hw raid cards...
http://www.linux-ide.org/chipsets.html
plain old ide controllers ( like promise/maxtor ) is $25 range...
- use only the master of each ide cable..
hda mirrored to hdd ( different ide controller )
hdc mirrored to hdb
if you are using 4 disks for raid1... you're better off in sw raid1
- cheaper...
- maybe faster.... ( lots of benchmarking to see for your setup )
