    Well, as I'm looking at this, I started a RAID-1 build about an hour 
ago (using the built-in raid controller) and it's at 31%, still 
building.  The drives are 500 GiB SATA drives.  When adding drives 
later, am I correct in assuming it's going to take just as long to build 
again?

    And if I choose to go with a linux managed RAID, is it also going to 
take as long to build the initial RAID and later when adding drives?

    The reason I ask is because we can't have this amount of down time 
when doing this.  I need to be able to run this machine with minimal 
downtime.  So I need to figure out a way to be able to add drives, grow 
the RAID, and at the same time keep running while this is all 
happening.  Sounds like having the BIOS manage the RAID is not the way 
to go because it takes too long.
