Abstract:
A method for improving data transfer rate performance of a disc drive in communication with a host device, the disc drive configured to store data from the host device in physical data blocks on at least one disc surface, the physical data blocks identified by the host device in terms of a corresponding sequence of logical block addresses (LBAs), the method comprising steps of:(a) providing input/output (I/O) commands to the disc drive comprising data access operations each directing the transfer of data between at least one LBA within the disc drive and the host device; (b) monitoring communications from the disc drive to the host device in response to the I/O commands; (c) correlating a time sequence of the I/O commands to the locations of the physical data blocks corresponding to the LBAs accessed by the I/O commands; and (d) adjusting at least one data transfer parameter of the disc drive in response to the correlation of time sequence and location of physical data blocks of step (c).
