Tim,

I would not use any RAID modes built into your SATA controller, AHCI or 
otherwise.  In doing so you're asking for trouble, lost RAID arrays, and 
lost data, plus it's a lot of unnecessary complexity (which almost 
certainly contributed to your earlier frustration and hair-pulling).  
For RAID I strongly recommend using the Linux kernel's built-in software 
RAID and letting the Linux kernel manage the RAID arrays.

This is about 15 years of sysadmin experience talking.  I use CentOS for 
everything.

Jim
