摘要： According to one exemplary embodiment, a method for storing and rebuilding data computes a corresponding parity after receiving an Input/Output command, and based on the parity, determines whether a final stripe corresponding to the Input/Output command is a full stripe. When the final stripe is a full stripe, a plurality of data and a parity corresponding to the Input/Output command are stored into a main hyper erase unit (HEU) in a disk storage system. When the final stripe is not a full stripe, a final parity is re-computed and written into at least two parity pages of a buffering HEU.
