For RAID, I have always recommended a HW solution even though it costs 
more.  The cost of the HW is not really significant compared to the 
value of the data.  SW RAID does work, but depends too much on the skill 
of the administrator.

As John says, a NAS is an excellent solution because it removes the 
dependence on a separate system and makes it easy for multiple systems 
to access the data.

I can't comment about the devices John mentions because I don't have any 
personal experience with them, but they sound like a good starting point.
