software raid1 ..though with only 1 drive it wont be very easy to setup the full system to be mirrored, easiest way to go on software raid1 is to setup a 500MB / partition, install minimal system, setup the raid array(s) and move the data over(i usually have /usr and /var and /home on raid, or 1 big /raid partition with /usr /var and /home pointing to /raid/usr /raid/var and /raid/home) i have never experienced a drive failure with software raid1 so i don't know what to expect if it were to occur. nate
