8.1 Introduction
To support demanding disk I/O, Intel® Q670E chipset integrates four serial ATA con-
trollers with software RAID 0, 1, 5, 10 capabilities.
RAID 0 striping increases storage performance and is designed to speed up data
transfer rates for disk-intensive applications.
RAID 1 mirroring protects valuable data that might be lost in the event of a hard drive
failure.
RAID 5 array contains three or more hard drives where the data is divided into man-
ageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. The data and parity are
striped across all the hard drives in the array. The parity is striped in a rotating
sequence to reduce bottlenecks associated with the parity calculations.
RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1.
The data is striped across a two-drive array forming the RAID 0 component. Each of
the drives in the RAID 0 array is then mirrored by a RAID 1 component.
