    [Three type of Parity calculations ]

    Read-peers reads each disk to calculate the

    parity, then performs XOR operations with the new data to calculate the new parity.

     

    Read modify-write reads only the current parity from the disk and the old data, then uses that information and the new data to calculate the new parity, reducing the number of read operations to two.

     

    Full stripe write, the fastest of the three

    methods, calculates parity directly from the

    data being written when that data is equal to

    the stripe size, eliminating the need to read any

    information from the disk.
