Internal SATA RAID Controller

This section covers the basics of what RAID does, how RAID works, and why you may
or may not want to use RAID. There are other means of creating a RAID drive on this
motherboard, such as through the Intel
which will be covered in more detail further below.
This motherboard supports several RAID modes over its eight (8) Intel
These RAID modes include RAID0, RAID1, RAID5, and RAID10, which tends to be
the standard for most motherboard-based RAID options.
Some basic understandings for this section:

All drives equal 1 Terabyte in size. Let's just make the math easy. In reality,
all drives are slightly less than what their labels show.

A physical drive is, essentially, the drive you installed in your system.

A logical drive is the drive "created" through RAID. In other words, this
virtual drive is what Windows sees.

Performance considerations are based on arrays using the same drive
model. Arrays comprised of drives with different performance
characteristics may see reduced performance and stability. There are many
factors outside the scope of this manual that can also affect performance.
ESSENTIAL RAID CONSIDERATIONS
 Please save yourself some time and effort by using drives with the same
make, model and capacity. Although it's tempting to use what you might
have lying around, mixing drives can lead to performance issues,
desyncing issues, data corruption, and ultimately array failure.
 Confirm that your drives support RAID. This may surprise people, but
drive manufacturers sometimes limit RAID support to specific models. If
a drive is not supported for RAID, the array may desynchronize
unexpectedly due to features missing that are necessary for
communication between drives in RAID.
