ASRock Rack WC422D8A-2T/U, EP2C612 WS Installation guide

  • Hello! I've reviewed the user manual for SATA Hard Disks, which provides guidance on installation and RAID configurations. The document covers RAID levels, including RAID 0, 1, 5 and 10, plus Intel Rapid Storage, as well as the process of setting up RAID using the Intel RAID BIOS. I'm ready to answer your questions about these devices and the content of this manual.
  • What RAID levels are supported?
    What is required for RAID 10 setup?
    What is the minimum number of drives required for RAID 5?
    What is the recommended configuration for RAID 0?

RAID
Theterm“RAID”standsfor“RedundantArrayofIndependent
Disks”,whichisamethodcombiningtwoormoreharddisk

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

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