I've spent a good part of my career working on such systems so I know 
exactly what you're talking about -- but I'm a software developer -- not 
the sysadmin that sets up the RAID stuff -- so the details here are new 
to me ;-)  As I said before, my requirements aren't for a high 
availability server -- just trying to reduce the window of possible data 
loss a little more.  If one of the 2 drives ever fail I could surely 
continue with no problem for a long time before replacing it.

Thx,

Jeff
