RAID1
: This type of array is referred to as "Mirroring" or a "Mirrored Array."
RAID1 uses two (2) physical drives and writes ALL data to both drives simultaneously
providing a 1 to 1 mirror, giving you a live 100% redundancy. If a drive fails while data
is being written, you will still be up and running. In most cases, when a failure occurs,
you will experience a stutter in performance and a small but noticeable slow down. Next,
you'll likely see a popup warning from IRST alerting you that a drive has failed or is
disconnected, and your array's status has been changed to "Degraded".
RAID1 (at least on these PCH driven controllers) are limited to 2 drives. Because this is
a mirror, you will use 50% of your capacity for redundancy.
The Good-

RAID1 allows you to suffer a catastrophic failure of 1 drive with no ill effects to
the data being stored.

Because data is stored on 2 drives at once, read speeds typically increase a little,
but not to the speed of RAID5 and, certainly, not to the speed of RAID0.
