DATA PROGRESSION DISK LOCALITY OPTIMIZATION SYSTEM AND METHOD

摘要

The present disclosure relates to disk drive systems and methods having data progression and disk placement optimizations. Generally, the systems and methods include continuously determining a cost for data on a plurality of disk drives, determining whether there is data to be moved from a first location on the disk drives to a second location on the disk drives, and moving data stored at the first location to the second location. The first location is a data track that is located generally concentrically closer to a center of a first disk drive than the second location is located relative to a center of a second disk drive. In some embodiments, the first and second location are on the same disk drive.
