RAID Overview
RAID (Redundant Array of Independent Disks) refers to multiple independent hard
drives combined to form one large logical array. With RAID in place, the operating
system (e.g. Windows* XP*) no longer deals with individual drives, but instead with
the entire disk array as one logical drives.
The major objectives of RAID are to improve data availability and security. This
version of the Intel Application Accelerator RAID Edition supports RAID Level 0.
RAID Levels 1, 4, 5, and 10 are currently not supported.
Installation CAUTION: When setting up RAID configurations and creating a
volume, it is important to understand that installing the Intel® Application
Accelerator RAID Edition on a system will DELETE ALL EXISTING DATA
from the RAID-controlled hard drive(s) and the data cannot be recovered. It is
important to backup all important data before proceeding with installation.
Uninstall CAUTION: It is important to understand that uninstalling the Intel®
Application Accelerator RAID Edition from a RAID-configured system will
DELETE ALL EXISTING DATA from the RAID-controlled hard drive(s) and
the data cannot be recovered. It is important to backup all important data before
uninstalling.
RAID Levels – How the Drives are organized
Each level of RAID spreads the data across the drives of the array in different way
and is optimized for specific situations.
RAID 0
RAID Level 0 combines two or more hard drives in a way that the data coming from
the user is cut into manageable blocks. These blocks are striped across the different
drives of the RAID 0 array. By doing this, two or more hard drives are combined and
the read/write performance, especially for sequential access, can be improved.
However, no redundancy information is stored in a RAID 0 array, which means that if
one hard drive fails, all data is lost. This lack of redundancy is also stated in the
number 0, which indicates no redundancy. RAID 0 is thus usually not used in servers
where security is a concern.

Appendix
RAID 0 Advantage: Highest transfer rates
RAID 0 Disadvantage: No redundancy – if one disk fails, all data will be lost
RAID 0 Application: Typically used in workstations for temporary data and high
I/O rate
