  • Patent number: 9280472
    Abstract: A combination of a host system and a storage system is disclosed that facilitates improved responsiveness of the host system to user requests. In one embodiment, the host system includes a cache management module, a partitioning module, and a driver. The cache management module determines write data to cache to a dedicated zone of a hard disk media of the storage system. The partitioning module partitions the hard disk media into one partition including the dedicated zone and another partition not including the dedicated zone. The driver transmits storage access commands to the storage system to cache data in and retrieve cached data from the one partition. Thereby, the host system can access the write data from the hard disk media more quickly than if the write data were cached in and accessed from another zone of the hard disk media.

  • Patent number: 8285965
    Abstract: A method of aligning a partition of a data storage device to a boundary of a physical data sector is disclosed. The data storage device comprises a non-volatile memory comprising a plurality of physical data sectors, wherein each physical data sector comprises a plurality of logical data sectors. A partition map is read from the non-volatile memory, wherein the partition map identifies a partition comprising a number of logical data sectors. A number of logical data sectors in each physical data sector is determined. Whether at least part of the partition aligns with a boundary of a physical data sector is determined. When at least part of the partition does not align with a boundary of a physical data sector, at least part of the partition is moved to align at least part of the partition to a boundary of a physical data sector.
