ABSTRACT:
The invention provides a method and system for staging write data to improve a storage system's performance. The method includes providing a write cache on the medium. The write cache includes a plurality of cache lines. Each of the cache lines includes a plurality of data blocks, line meta-data to identify each data blocks sector address, and a sequential number indicating the order of the data blocks within their respective cache line relative to the other data blocks in the cache line. In addition, the method includes staging write data in the write cache as sequentially written data to improve performance of the system. The staging includes receiving a plurality of data blocks to be written to the system. Moreover, the staging includes storing the data blocks in one of the cache lines.
