Abstract
A stream classification system of a data storage device monitors an access frequency of data stored by the data storage device. If the data is classified as cold data, the stream classification system rewrites the cold data to a primary storage partition using one or more special data storage parameters. The one or more special data storage parameters cause the cold data to be more resilient to various data storage issues including, but not limited to, data retention issues, read disturb issues and/or temperature cross issues.
