1. Introduction of RAID This motherboard adopts a chipset that supports RAID. The term "RAID" stands for "Redundant Array of Independent Disks", which is a method of combining two or more hard disk drives into one logical unit. For optimal performance, please install identical drives of the same model and capacity when creating a RAID set. The following are common examples of RAID. Please refer to the user manual for the types of RAID your motherboard supports, and notice that other requirements such as a RAID supporting disk drive and operating system are also crucial for creating a RAID volume. RAID 0 (Data Striping) RAID 0 is called data striping that optimizes two identical hard disk drives to read and write data in parallel, interleaved stacks. It will improve data access and storage since it will double the data transfer rate of a single disk alone while the two hard disks perform the same work as a single drive, but at a sustained data transfer rate and it has no fault tolerance. RAID 1 (Data Mirroring) RAID 1 is called data mirroring that copies and maintains an identical image of data from one drive to a second drive. It provides data protection and increases fault tolerance to the entire system since the disk array management software will direct all applications to the surviving drive as it contains a complete copy of the data in the other drive if one drive fails. 2

Introduction of RAID
Th±s motherboard adopts a
ch±pset that supports RAID.
The term “RAID” stands for “Redundant Array of Inde
-
pendent D±sks”, wh±ch ±s a method of comb±n±ng two or
more hard d±sk dr±ves ±nto one log±cal un±t. For opt±mal
performance, please ±nstall ±dent±cal dr±ves of the same
model and capac±ty when creat±ng a RAID set. The fol
-
low±ng are common examples of RAID. Please refer to
the user manual for the types of RAID your motherboard
supports, and not±ce that other requ±rements such as a
RAID support±ng d±sk dr±ve and operat±ng system are
also cruc±al for creat±ng a RAID volume.
RAID 0 (Data Str±p±ng)
RAID 0 ±s called data str±p±ng that opt±m±zes
two ±dent±cal hard d±sk dr±ves to read and
wr±te data ±n parallel, ±nterleaved stacks.
It w±ll ±mprove data access and storage
s±nce ±t w±ll double the data transfer rate of
a s±ngle d±sk alone wh±le the two hard d±sks
perform the same work as a s±ngle dr±ve,
but at a susta±ned data transfer rate and ±t
has no fault tolerance.
RAID 1 (Data M±rror±ng)
RAID 1 ±s called data m±rror±ng that cop±es
and ma±nta±ns an ±dent±cal ±mage of data
from one dr±ve to a second dr±ve. It pro
-
v±des data protect±on and ±ncreases fault
tolerance to the ent±re system s±nce the
d±sk array management software w±ll d±rect
all appl±cat±ons to the surv±v±ng dr±ve as ±t
conta±ns a complete copy of the data ±n the
other dr±ve ±f one dr±ve fa±ls.
