摘要
Method and apparatus for improving data transfer rate performance of a disc drive configured to store data from a host device in physical data blocks identified by the host device in terms of logical block addresses (LBAs). A sequence of input/output (I/O) commands is provided to the disc drive each directing the transfer of data between at least one LBA within the disc drive and the host device. The correlation between the 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 is obtained, and preferably displayed graphically in a three-dimensional histogram showing physical data block accesses by time and by frequency. At least one data transfer parameter of the disc drive is thereafter adjusted in relation to the physical operations of the drive in response to the I/O command sequence.
