The RAID configuration is really a moot point. As long as you remove the single point of failure for your drive then you should be fine. RAID 1 is just fine and is usually the most cost effective RAID configuration.

Then to make sure your backup isn't a single point of failure (IE if your shop was robbed/burned/bombed and the computer taken/destroyed...then so is your data)

Use microsoft's built-in backup utility to do a backup of system state and critical data to another computer or hard drive (like the USB drive).

Then if you are really paranoid use ghost or some other imaging software and take a monthly or bi-monthly image of the drive and burn the image to dvd's and take them off-site.


Oh and sorry to hear about the drive failure. I just had that happen with a Maxtor that I was in the middle of putting all my cd's and dvd's onto to make my home theater media-less. And now it's all gone. :evil:
