1. Introduction of RAID
Thismotherboardadoptsa chipsetthatsupportsRAID.
Theterm“RAID”standsfor“RedundantArrayofInde-
pendent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fol-
lowing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pro-
vides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.

RAID 10
RAID10isastripedcongurationwithRAID1seg-
mentswhosesegmentsareRAID1arrays.Thiscon-
gurationhasthesamefaulttoleranceasRAID1,and
hasthesameoverheadforfault-toleranceasmirroring
alone.RAID10achieveshighinput/outputratesby
stripingRAID1segments.Insomeinstances,aRAID
10congurationcansustainmultiplesimultaneousdrive
failure.Aminimumoffourharddiskdrivesisrequired
forthissetup.
RAID 5
RAID5stripesbothdataandparityinformationacross
threeormoreharddiskdrives.Amongtheadvantages
ofRAID5congurationincludebetterHDDperfor-
mance,faulttolerance,andhigherstoragecapacity.
TheRAID5congurationisbestsuitedfortransaction
processing,relationaldatabaseapplications,enterprise
resourceplanning,andotherbusinesssystems.Use
aminimumofthreeidenticalharddiskdrivesforthis
setup.

RAID Conguration Precautions
1. Pleaseusetwonewdrivesifyouarecreating
aRAID0(striping)arrayforperformance.Itis
recommendedtousetwoSATAdrivesofthe
samesize.Ifyouusetwodrivesofdifferent
sizes,thesmallercapacityharddiskwillbethe
basestoragesizeforeachdrive.Forexample,
ifoneharddiskhasan80GBstoragecapa-
cityandtheotherharddiskhas60GB,the
maximumstoragecapacityforthe80GB-drive
becomes60GB,andthetotalstoragecapacity
forthisRAID0setis120GB.
2. Youmayusetwonewdrives,oruseanexi-
stingdriveandanewdrivetocreateaRAID1
(mirroring)arrayfordataprotection(thenew
drivemustbeofthesamesizeorlargerthan
theexistingdrive).Ifyouusetwodrivesofdiffe-
rentsizes,thesmallercapacityharddiskwill
bethebasestoragesize.Forexample,ifone
harddiskhasan80GBstoragecapacityand
theotherharddiskhas60GB,themaximum
storagecapacityfortheRAID1setis60GB.
3. Pleaseverifythestatusofyourharddisksbe-
foreyousetupyournewRAIDarray.
4. Pleasebackupyourdatarstbeforeyoucre-Pleasebackupyourdatarstbeforeyoucre-
ateRAIDfunctions.Intheprocessyoucreate
RAID,thesystemwillaskifyouwantto“Clear
DiskData”ornot.Itisrecommendedtoselect
“Yes”,andthenyourfuturedatabuildingwill
operateunderacleanenvironment.

2.1 Install the hard disk drives
Connecttwoormorenewharddiskdrivesofthesame
modelandcapacitytoyoursystem.
 BeforecreatingaRAIDarray,pleasechecktheusermanualfor
informationof:
 1.WhatlevelsofRAIDdoesyourmotherboardsupport
 2.WhichSATAportssupportRAID
 3.Otherrelatedrequirements
2.2 Set up UEFI
EnterUEFISETUPUTILITYAdvancedscreen
 StorageConguration.Set“SATAModeSelection”to
[RAID].

2.3 Congure Intel RAID BIOS
Rebootyourcomputer.Press<Ctrl+I>toentertheRAID
BIOSwhenyouseetheRAIDsoftwarestatusscreen.
 SelecttheoptionCreate RAID Volumeandpress
<Enter>.
 IntheCreateVolumeMenu,pleaseinsertaunique
nameforyourRAIDvolume.

7
 SelectyourdesiredRAIDLevel.
 IfyouselectedRAID0(Stripe),youarerequired
toselectthestripesizeforyourRAID0array.The
availablevaluesrangefrom8KBto128KB.Thedefault
selection is 128 KB. The strip value should be chosen
basedontheplanneddriveusage.
•8/16KB-lowdiskusage
•64KB-typicaldiskusage
•128KB-performancediskusage

8
 Aftersettingstripsize,setthediskCapacity.
 Press <Enter> and then Press <Y> to continue when
theutilitypromptsaconrmationmessage.
 Aftertheconfiguration,youwillseethedetailed
informationabouttheRAIDarraythatyousetup.

9
 PleasenotethatyouareonlyallowedtocreateoneRAID
partitionatatimeunderBIOSRAID.Ifyouwanttocreate
an extraRAIDpartition,pleaseusetheRAIDutilityunder
WindowstocongureRAIDafteryouinstalltheOS.
 IfyouwanttodeleteaRAIDvolume,pleaseselectthe
option Delete RAID Volume, press <Enter>, and then
followtheinstructionsonthescreen.

3. Installing Windows® on a HDD under 2TB in
RAID mode
 After the UEFI andRAIDBIOSsetup you may start
installingWindows® 7 / 7 64-bit / VistaTM / VistaTM 64-
bit OSasusual.

11
4. Installing Windows® on a HDD larger than
2TB in RAID mode
 Windows®VistaTM/7doesnotsupportHDD’slargerthan2TB.
PleasemakesuretouseWindows® VistaTM 64-bit (with SP2
or above) or Windows® 7 64-bit.
AftertheUEFIandRAIDBIOSsetup,pleasefollowthe
stepsbelow.
STEP 1: Copy Intel® RAID drivers into a USB ash
disk
 You can download the drivers fromASRock's website
andunzipthelesintoaUSBashdiskorcopytheles
fromASRock's motherboard support CD. (Please copy
thelesunderthefollowingdirectory:
32bit:..\i386\Win7_Vista_Intel..
64-bit:..\AMD64\Win7-64_Vista64_Intel..
STEP 2: Install Windows® VistaTM 64-bit / 7 64-bit OS
Press<F11>tolaunchbootmenuatsystemPOSTand
choosetheitem“UEFI:<Opticaldiskdrive>“toboot.

12
 Start Windows® Installation. When you see “Where do
youwanttoinstallWindows?”page,pleaseclick“Load
Driver”.
 PlugtheUSBflashdiskintoyourUSBport;select
“Browse”tofindtheRAIDdriver.Thenchoosethe
directoryyouhavecopiedintherststep.
 PleasekeeptheUSBflashdiskinstalleduntilthe
system'sfirstreboot.ContinuetoinstalltheOSby
followingtheinstructions.

13
IfyouinstallWindows®764-bit/VistaTM64-bitonalargeharddisk(ex.
Diskvolume>2TB),itmaytakemoretimetobootintoWindows®orinstall
driver/utilities.Ifyouencounterthisproblem,youwillneedtofollowthe
instructionsbelowtoxthisproblem.
