Abstract
Implementations disclosed herein provide for a storage system including an on-disk read cache and a variety of read cache management techniques. According to one implementation, a storage device controller time-sequentially reads a series of non-contiguous data blocks storing a data sequence in a read cache of a magnetic disk, the data sequence identified by a requested sequence of logical block addresses (LBAs). The controller determines that read requests for the data sequence satisfy at least one predetermined access frequency criterion and, responsive to the determination, the controller re-writes data of the data sequence to a series of contiguous data blocks in the read cache.
