Based on my RAID research I have determined I will start with software RAID in a RAID 5 or 1+0 configuration. I still want to research RAID 6 which seems to be in vogue right now.
Taking a break from storage I started to slim the file server list down and the follow potential solutions were cut from my list:
Miracle Linux - No English Documents Found
Nitix - Software is a trial version only
Server Optimized Linux - Only RAID 1 supported and limited documentation
TinySofa - No Documents Found
TupiServer - No English Documents Found
SLAMPP Live CD
