• RAID 6 (redundant array of independent disks)

    RAID 6, also known as double-parity RAID, uses two parity stripes on each disk. It allows for two disk failures within the RAID set before any data is lost.

  • RAID 3 (redundant array of independent disks)

    RAID 3 is a RAID configuration that uses striping and parity, but it uses a parity disk to store the parity information generated by a RAID controller instead of striping it with the data.

  • RAID 2

    RAID 2 is a technique that stripes data at the bit level using a Hamming code to detect errors.

  • RAID 0 (disk striping)

    RAID 0, also known as disk striping, is a technique that breaks up a file and spreads the data across all the disk drives in a RAID group.
