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.
