DISK STORAGE PERFORMANCE USING DIGITAL MEMORY AND DATA COMPRESSION

摘要

Enhancing performance of hard disk-based storage using large amounts of digital memory is described, including determining available storage capacity of a flash memory and a hard disk, identifying data to be stored in at least the flash memory, remapping the data, the data being stored in at least the flash memory after the remapping is performed, generating a copy of the data stored in the flash memory, and storing the copy of the data on the hard disk as a mirror of the data Data compression may also be used to enhance performance by compressing data to be written to a digital memory, increasing the amount of data that can be stored in a digital memory. Data compression may also be used to compress data written into a hard disk drive, which improves performance because less data is written and subsequently read from the hard disk.
