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 HDD in the array times
however many HDDs are in the array. Any larger HDDs will simply be truncated. The
truncated space on the bigger HDDs will then be unusable.
For sustained data transfers --
A RAID 0 array consisting of two HDDs will transfer at about
twice the speed of the slowest HDD in the array. A RAID 0 array consisting of four HDDs will
transfer at about three times the speed of the slowest HDD in the array.
RAID 1 (mirror)
For capacity –
This Motherboard array will be as big as the smallest HDD in the array. The
larger HDD will simply be truncated. The truncated space on the bigger HDD will then be
unusable.
For sustained data transfers --
This motherboard array will write data at the rate of the slowest
HDD in the array. This motherboard array will read data at twice the rate of the slowest HDD
in the array.
