Abstract
Managing data in a data storage system including at least one Data Storage Device (DSD) and a host. An initial location is determined for data to be stored in the at least one DSD based on at least one attribute defined by the host. A source portion is identified from a plurality of source portions in the at least one DSD for a garbage collection operation based on the at least one attribute defined by the host. A destination portion is identified in the at least one DSD for storing data resulting from the garbage collection operation based on the at least one attribute defined by the host. Garbage collection of the data in the source portion is performed into the destination portion, and after completion of garbage collection, the source portion is designated as a new destination portion for a new garbage collection operation.
