  • Method and apparatus for storage application programming interface for digital mass storage and retrieval based upon data object type or size and characteristics of the data storage device
    Patent number: 6128717
    Abstract: A storage application programming interface (SAPI) engine is included in a hard disk drive (HDD). The SAPI engine operation is based on intelligent recognition of a plurality of different data objects characterized by type and/or size. The SAPI engine assigns a SAPI descriptor to data objects during its analysis recognition process. The SAPI descriptor identifies the type of the data object, and is used by the HDD to map the data object to a unique logical object address (LOA) space of the HDD tailored to characteristics of the particular disk drive. Using the SAPI descriptor assigned by the SAPI engine enables the HDD to more efficiently store data objects being sent by applications on a host computing system to the disk drive. The efficient storage by the HDD provides a system having improved access performance.
