What Is Raid And What Are Different Types Of Raid Configurations?

Answer»

RAID stands for Redundant Array of Independent Disks. RAID defines data STORAGE schemes to divide and replicate data among various disks so that data reliability and I/O performance can be increased.

The BASIC configurations of RAID are:

  • LEVEL 0: Striped set without parity/Non-Redundant Array.
  • LEVEL 1: Mirrored set without parity.
  • LEVEL 2: REDUNDANCY through HAMMING code.
  • LEVEL 3: Striped set with dedicated parity/Bit interleaved parity.
  • LEVEL 4: Block level parity.
  • LEVEL 5: Striped set with distributed parity.
  • LEVEL 6: Striped set with dual distributed Parity.
