That's very good to hear. It appears that old drives did silent
corruption, but new drives don't. All my drives are relatively new, so I
should be fine there.

Thanks for the tip. I will definitely use that.
I am attracted to RAID 1 because of the simplicity, but RAID 5 would
give me more redundant storage at the expense of some non-redundant
storage. In my situation, with 2x 120GB and 1x 250GB, what do you
recommend?
Also, is it a good idea to boot on SW-RAID? It can be done, but is it
wise?
Thanks again for your help,
Evan

I'm too much of a whippersnapper to know what those mean, but I probably
don't miss them either :-)
