RAID

Theterm“RAID”standsfor“RedundantArrayofIndependent

Disks”,whichisamethod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.

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.

WARNING!!

AlthoughRAID0functioncanimprovetheaccessperformance,

it does not provide any fault tolerance. Hot-Plug any HDDs of

theRAID0Diskwillcausedatadamageordataloss.

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
