ASRock Rack E3C242D4U2-2T Installation guide

  • Hello, I am your assistant, I have read the user manual for the ASRock E3C242D4U2-2T SATA Hard Disks. This document provides instructions for installing SATA hard disks and configuring various RAID arrays, including RAID 0, 1, 5, 10 also Intel Rapid Storage. I'm ready to answer your questions about the device and its RAID setup.
  • What RAID levels are supported?
    What is a minimum of number of hard disk drives needed for RAID 10 setup?
    Is it necessary to use the same size hard drives for RAID?

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

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