Abstract:
A method for improving performance of a read cache of a disk drive, comprising:a data transmission process for reading corresponding data from a disk in response to a data read command of a host computer, temporarily storing said corresponding data in a constant unit storage region of a data transmission storage device, and transmitting said corresponding data to said host computer; a first read cache process for reading, from said disk, first data corresponding in size to said constant unit storage region and taken from a series of data after said corresponding data, and storing said first data in said constant unit storage region; and a second read cache process for reading, from said disk, second data corresponding in size to a multiple of said constant unit storage regions and taken from a series of data after said first data, and storing said second data in all other constant unit storage regions of said data transmission storage device.
