Abstract: An exemplary write method disclosed herein includes receiving a request to write data to a consecutive sequence of logical block addresses (LBAs) that is the mapped to a non-contiguous sequence of data tracks on a storage medium, and writing the data of the consecutive sequence of LBAs to a non-contiguous sequence of data tracks on the storage medium and according to a consecutive track order.

Abstract: A method or system for allocating the storage space of a storage medium into a permanently allocated media cache storage region, a dynamically mapped media cache storage region, and statically mapped storage region. In one implementation, the dynamically mapped media cache storage region is used for performance and/or reliability enhancing functions.

Abstract: A method for improving write throughput of a storage device includes receiving a data access command targeting an LBA extent and determining that logical execution of the data access command includes reading or writing data logically across an identified high-performance-cost boundary. Responsive to the determination, the data access command is split into two or more separate data access commands that are separately queued in memory for execution.

Abstract: In accordance with one implementation, a method for reducing cache service time includes determining an access time parameter associated with movement of a read/write head to an access location for each of a plurality of contiguous cache storage segments and dynamically selecting one of the plurality of contiguous cache storage segments to store data based on the determined access time parameter.

Abstract: A storage device or storage system includes a transient compression layer that is established based on a level of finishedness of the capacity of the storage device or storage system. Data may be compressed and written to the transient compression layer until the capacity is sufficiently finished, after which the compressed data may be destaged and written to the capacity. The transient compression layer may be established on a hard disc media of the storage system or in a SSD of the storage system.
