6 Using RAID and ASF 2.0
6.1 About RAID
NOTE: You need to install two Serial ATA hard disk drive and running Windows XP or
Windows 2000 in order for your system to support RAID (Redundant Array of Inexpensive
Disk).
The purpose of RAID is to combine multiple small, inexpensive disk drives into an
array of disk drives that appears to the system as a single logical storage device and
yields performance exceeding that of a Single Large Expensive Drive (SLED).
Your system provides the Intel Application Accelerator for creating your array. There
are two types of array architectures that you can create:
l RAID 0
In this type, data is split across drives, resulting in higher data throughput.
Performance is good but the failure of any disk in the array results in data loss.
This type is commonly referred to as striping.
l RAID 1 (Recommended)
In this type, data are written to two drives. If either drive fails, no data is lost. This
type is commonly referred to as mirroring.
CAUTION: If creating a Security array using an existing hard drive, back up any necessary
data. Failure to follow this could result in data loss.
