RAID Introduction

What is RAID?
This motherboard implements two different types of RAID levels as follows:
RAID 0 (stripe)
For capacity -- The motherboard array will be as big as the smallest H DD in the array times however
many H DDs are in the array. Any larger H DDs will simply be truncated. The truncated space on
the bigger H DDs will then be unusable.
For sustained data transfers -- A RAID 0 array consisting of two H DDs will transfer at about twice the
speed of the slowest H DD in the array. A RAID 0 array consisting of four H DDs will transfer at about
three times the speed of the slowest H DD in the array.
RAID 1 (mirror)
For capacity - This Motherboard array will be as big as the smallest H DD in the array. The larger
H DD will simply be truncated. The truncated space on the bigger H DD will then be unusable.
For sustained data transfers -- This motherboard array will write data at the rate of the slowest H DD in
the array. This motherboard array will read data at twice the rate of the slowest H DD in the array.
