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.
