ABSTRACT:
A method and apparatus for storing associated data in a computing system having two or more storage devices arranged in a RAID configuration. The storage devices have a prewrite area for pre-storage of the data, and data region for persistent storage of the data. A scoreboard memory structure is created for monitoring the state of the prewrite area, and data in the prewrite area is conditionally invalidated based upon the information contained in the scoreboard memory structure. By conditionally invalidating the prewrite data, the write performance of the RAID storage system is improved.
