Intel ICH9R SATA RAID

(1) Step 1: Configure Volume
Here you can configure the new RAID volume by entering the volume name, selecting

the RAID level and strip size.

RAID Volume Name:

A desired RAID volume name needs to be typed in where the ‘RAID_Volume1’ text

currently appears above. The RAID volume name has a maximum limit of 16 characters.

The RAID volume name must also be in English alphanumeric ASCII characters.

RAID Level:

Select the desired RAID level:

RAID 0

(Performance) – A volume optimized for performance will allow you to

access your data more quickly.

RAID 1

(Redundancy) – A volume optimized for data redundancy will provide

you with a realtime duplicate copy of your data. Note:

Only half of the available volume space will be avail-

able for data storage.

RAID 5

(Useful) –

RAID 5 can be used on three or more disks, with zero

or more spare-disks. The resulting RAID-5 device size

will be (N-1)*S, where N is the how many drive, S is the

size of the smallest drive in the array. If one of the disks

fail, all data are still intact. It can rebuild the disk from

the parity information. If spare disks are available, re-

construction will begin immediately after the device

failure. If two disks fail simultaneously, all data are lost.

RAID-5 can survive one disk failure, but not two or

more. Both read and write performance usually

increase, but can be hard to predict how much. Reads

are similar to RAID-0 reads, writes can be either rather
