• 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.

  • double-parity RAID

    Double-parity RAID (redundant array of independent disks), also called diagonal-parity RAID, Advanced Data Guarding (RAID_ADG), or RAID-6, is a method of protecting against multiple storage drive failures by creating two sets of parity data on an arr...

    Disk duplexing is a variation of disk mirroring in which each of multiple storage disks has its own SCSI controller. 

  • disk striping

    In computers that use multiple hard disk systems, disk striping is the process of dividing a body of data into blocks and spreading the data blocks across several partitions on several hard disks.

  • RAID-1 vs. RAID-5

    Can I install an operating system (OS) and put data in different partitions of RAID-5, or is RAID-1 (hardware-based RAID) a better solution? Is it ok if we divide a RAID into two partitions? Does RAID-5 take a long time to rebuild?
