Abstract
A storage device implements a method for garbage collection. The storage device arranges data blocks of a storage medium into a bin and determines first coldness of a first data block in the bin and second coldness of a second data block in the bin that are respectively associated with a first rate of change of valid data in the first data block into invalid data and a second rate of change of valid data in the second data block into invalid data. Based on the first coldness and the second coldness, the storage device selects a colder data block from the first and second data blocks as a garbage data block. Because the valid data in the selected garbage data block are more stable, they may cause less new stale data or garbage data in a new block to which the valid data are moved.
