Abstract
Systems, methods, and software are disclosed herein that enhance data storage operations. In various implementations, a preserve write process identifies one or more regions of the solid-state memory components that qualify to be relocated prior to a data storage device entering a data retention state. Prior to the data retention state, the process changes one or more values, of one or more write settings, to one or more new values. With the write settings changed to the one or more new values, the process relocates data from the one or more regions to one or more new regions. After having relocated the data, the process returns the one or more new values, of the one or more write settings, to one or more earlier values.
