2.4 RAID 10 (RAID 1+0)
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.
Hard Drives
Required:
4
Advantage:
Combines the read performance of RAID 0 with the fault-tolerance of RAID 1.
Fault-tolerance:
Excellent – disk mirroring means that all data on one disk is duplicated on another disk.
Application:
High-performance applications requiring data protection, such as video editing. Not
available in mobile configurations.

2.5 Matrix RAID (Two Volumes Per Array)
Matrix RAID allows you to create two RAID volumes on a single RAID array.
As an example, on a systems 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. This is shown in Figure 5.
