Abstract

Systems and methods are disclosed for determining whether data to be written to a memory should be deduplicated. In some implementations, a method is provided. The method includes determining whether data to be written to a memory should be deduplicated based, at least in part, on status information of a controller and media characteristics of the memory, wherein the status information of the controller indicates a level of resources available for a deduplication operation. In response to determining that the data should be deduplicated, determining whether the data is duplicative based on the type of memory the data is being written to.
