Important Note About This Guide
Note: This guide contains information common to all VAIO models that can
be configured for RAID. For detailed information about your specific com-
puter, go to VAIO Support Central and select Product Specification, or con-
tact VAIO Customer Service.
Why Use RAID?
The main objectives of RAID are to improve data availability and security.
With everything from basic file and print services to e-Commerce and
important business applications running on server-based networks, reliable
and secure access to data is becoming a critical issue for everyone.
A RAID system can improve your VAIO
improving data availability and security. RAID prevents downtime in the event
of a hard disk failure by storing your data on multiple hard disks.
Note: Your VAIO
S-ATA hard disk drives. Sony recommends using hard disk drives that are
identical in size and manufacture.
Benefits of RAID
The degree that you realize the various benefits listed below depends on the
exact type or level of RAID that you choose. However, you will always get
some combination of the following benefits
Higher Data Security
Most RAID levels provide protection for the data stored on the array through
the use of redundancy. This means that the data on the array can withstand
the failure of one hard disk (or sometimes more) without any data loss, and
without requiring any data to be restored from backup.
Fault Tolerance
RAID implementations that include redundancy provide you with a more
reliable overall storage system than can be achieved by a single disk. This
means there is a lower chance of the storage system (as a whole) failing due
to hardware failures.
