ABSTRACT:
A method and apparatus are provided for improving write throughput in a redundant array of mass storage devices using a cache memory to store redundant terms or code words generated when data is written to one or more devices in the array. The cache memory improves the write-throughput performance of the array by eliminating the need to perform a read-modify-write operation on check data stored in the mass storage devices of the array each time a write request is made. As a result, write-throughput of the system, particularly at peak demand periods, is improved.
