Installing WinXP & Win2K With RAID
RAID Description
RAID:
Short for Redundant Array of Independent (or Inexpensive) Disks, a category of
disk drives that employ two or more drives in combination for fault tolerance and
performance. RAID disk drives are used frequently on servers but aren't gener-
ally necessary for personal computers.
RAID 0 (there is number 0 of RAID level): Provides data striping (spreading out
blocks of each file across multiple disks) but no redundancy. This improves
performance but does not deliver fault tolerance.
This motherboard supports Intel
® RAID0 through the ICH5R chipset.
Characteristics:
1. RAID 0 implements a striped disk array, the data is broken down into blocks
and each block is written to a separate disk drive.
2. I/O performance is greatly improved by spreading the I/O load across many
channels and drivers.
3. Best performance is achieved when data is striped across multiple controllers
with only one drive per controller.
Advantages:
1. No parity calculation overhead is involved.
2. Very simple design.
3. Easy to implement.
Disadvantages:
1. Not a "True" RAID because it is NOT fault-tolerant.
2. The failure of just one drive will result in all data in an array being lost.
3. Should never be used in mission critical environments.
Setting up the RAID function in BIOS setup:
Please refer to RAID Description before setting up the RAID function.
