Abstract
Disclosed embodiments are directed to systems and methods for improving garbage collection and wear leveling performance in data storage systems. The embodiments can improve the efficiency of static wear leveling by picking the best candidate block for static wear leveling and/or postponing static wear leveling on certain candidate blocks. In one embodiment, one or more source blocks for a static wear leveling operation are selected based at least on whether the one or more blocks have a low P/E count and contain static data, such as data that has been garbage collected.
