Thanks Andrew,

That certainly goes along with the results of my testing on this unit.

Would you happen to know if I purchased a Promise card, is it capable of 
auto-rebuilding the mirror when a drive is replaced, or does that have 
to be done at the console using the board's BIOS?

I've been using vinum for years, but I am now spoiled by my DAC960 cards 
and how they will auto-rebuild a replaced drive.  I think ATA RAID 
controllers have a long way to go...
