The array depictions below show how this issue scales to larger arrays. In fact, due to
the lack of fault tolerance, the potential failure rate actually increases because of the
addition of more drives that can physically fail.
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 alertin
g 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 in redundancy.
