1-1 What is RAID?
The RAID Fuction is designed to provide a cost-effective, high performance
RAID technology that adds performance and/or reliability to PC desktops
and/or servers using Ultra ATA/133, Ultra ATA/100, Ultra ATA/66, or EIDE
drives.(By Function)
RAID Function of the mainboard supports striping (RAID 0) or mirroring (RAID 1)
for master only. Please note the function supports hard disk drives only.
With striping, identical drives can read and write data in parallel to increase
performance. Mirroring increases read performance through load balancing
and elevator sorting while creating a complete backup of your files.
An ATA133 RAID striped array can double the sustained data transfer rate of
Ultra ATA/133 drives. RAID fully supports Ultra ATA/133 specification of up to 133
MB/sec per drive, depending on individual drive specifications.
The RAID technology also offers fault tolerant, data redundancy for entry-level
network file servers or simply for desktop PC users wanting to continually
protect valuable data on their PC. The RAID Function offers RAID 1 mirroring
(for two drives) to protect data. Should a drive that is part of a mirrored array
fail, RAID technology uses the mirrored drive (which contains identical data) to assume
all data handling. When a new replacement drive is later installed, RAID Function
rebuilds data to the new drive from the mirrored drive to restore fault tolerance.
ATA133 RAID's bootable BIOS supports individual drives larger than 128GB.(For
20276 chipset) ATA100 RAID's bootable BIOS supports individual drives larger than
8.4GB.(For 20275chipset) With FAT32 and NTFS partitioning, the array can be
addressed as one large single volume.
