RAID
  1. What is RAID?
    1. RAID or Redundant Array of Independent Disks is used for additinoal backing storage and redundancy for a computer systems
      1. RAID is used for redundancy for when a drive fails. RAID can also be used to increase the overall storage space by combining low capacity drives.
      2. Types of RAID
        1. RAID 1
          1. This array mirrors the same data across multiple drives. The advantages of using this are the same as RAID 0, however all data can be recovered if one drive fails. The disadvantage is that only half of the capacity can be used with damaged drives not being able to be hot swapped whilst in operation.
          2. RAID 5
            1. RAID 10
              1. RAID 0
                1. This stripes data across two drives. The advantages of using RAID 0 are that it is good read and write speeds and a RAID card is rarely needed. The disadvantages are that it has no fault tolerance, which means that is one drive dies all the data is lost
