Hrm... I didn't implicitly attempt to call you stupid. I was asking a 
question, and laying out info for others that may not know as they 
follow the thread...

Besides...if you are seriously considering a 7TB storage facility, then 
you already know that building a proper RAID solution should include 
controllers that are hot-swappable, and will rebuild the array either as 
soon as you pop a new drive in, or with a hot-spare, without having to 
reboot and waste three hours rebuilding via a BIOS software.
