RAID 10
A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1.
It is a striped set whose members are each a mirrored set.
Table 4 provides an overview of the advantages, the level of fault-tolerance provided,
and the typical usage of RAID 10.

Matrix RAID allows you to create two RAID volumes on a single RAID array.
As an example, on a system with an Intel® 82801GR I/O controller hub (ICH7R),
Intel® Matrix Storage Manager allows you to create both a RAID 0 volume as well as
a RAID 5 volume across four Serial ATA hard drives.
Example: Refer to Figure 1.
