A storage device may be configured to copy valid data units from a source memory area to a destination memory area according to a source-to-destination mapping. The source-to-destination mapping may be generated based on a ranking scheme that considers the number of valid data units being stored in each of a plurality of source pages storing the data.

Managing data stored in a nonvolatile storage device

A data storage device includes a memory. A method includes de-allocating a first region of a group of regions of the memory during a wear leveling process based on a determination that the first region is associated with a first tag of a set of tags. Each region of the group of regions is assigned to a tag of the set of tags based on a health metric associated with the region. The health metric is based on a bit error rate (BER), a program/erase cycle (PEC) count, a PEC condition metric, or a combination thereof. In response to selecting the first region, information is copied from the first region to a second region of the memory during the wear leveling process.
