  • Define and describe RAID
    Redundant Array of Independent Disks, is a technology that uses multiple disks to increase performance and/or redundancy
  • What is RAID 0?
    Striping, data is split between multiple disks to increase read and write speeds, no redundancy
  • What is RAID 1?
    Mirroring, data is duplicated between multiple disks to create redundancy without increasing performance
  • What is RAID 5?
    Striping with parity, stripes data while reserving a block for parity to ensure redundancy, a middle-ground solution between RAID 0 and RAID 1, requires at least 3 drives
  • What is nested RAID?
    Using multiple RAID configurations in the same RAID array
  • What is RAID 10?
    RAID 1+0, a nested RAID configuration that stripes and mirrors data, requires at least 4 drives
  • What is RAID 50?
    RAID 5+0, a nested RAID configuration that mirrors a RAID 5 array, requires at least 6 drives
