  • Data pattern caching for speeding up write operations
    Patent number: 5991847
    Abstract: A data pattern cache stores data patterns in units (i.e., a sector). A given data pattern is associated with one or more physical device address ranges which store such data pattern (e.g., sectors). Thus, although the same data pattern may occur as 10 redundant sectors for different files on different parts of a hard disk, the data pattern is stored in the data pattern cache once. One or more physical device sectors are linked to the data pattern.
