RAID

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

Disks”,whichisamethodcombiningtwoormoreharddisk

RAID 0 (Data Striping)

RAID0iscalleddatastripingthatoptimizestwo

WARNING!!

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

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

RAID 1 (Data Mirroring)

RAID1iscalleddatamirroringthatcopiesand
