Absolutely.  Some raid controllers you can in fact figure out how they
wrote the disks and recover, but not simple.

Software raid does need a higher skill level to manage though,given
changing disks and doing rebuilds isn't plug and play the way it is on
hardware raid in general.  Software raid can be faster and much more
flexible though.

I certainly have both in different setups (or in the case of my mythtv
box, it actually has both in one system.)
