I disagree.  In a RAID 1 setup your max throughput is the speed of a single
drive.  In RAID 5, it will almost always be higher is you have even 3
drives, because of the striping across all three.  When you account for the
overhead of writing the parity info, you still get slightly higher
throughput than a RAID 1 setup.  This performance increases with the number
of drives you add to the stripe.

RAID 1, for fault-tolerance and speed.  Raid 1 will be faster than raid = 5.

The AD database will not grow large enough that you will need multiple =
disks and form a raid 5 subset... But if you do, and you get yourself a =
decent controller you could always convert from Raid 1 to 5 on the fly.

Building a 2000 DC in a pristine domain. What would most of you = recommend
on=20 the DC for fault tolerance, RAID 1 or RAID 5 and why?
