I've always liked the simplicity of software RAID1.  You lose some disk 
capacity (pretty cheap these days) compared to RAID5 and if you use a 
simple scheme keeping the disks independent you will have to deal with 
multiple mount points.   In return, you get the ability to easily 
recover the data from any single disk and to make a backup by swapping 
out one of the mirrors and sync'ing to a new one.  Plus, you don't have 
to worry about matching up with the old controller if you want to move a 
disk or a set.
