Summary:Disclosed embodiments are directed to systems and methods for dynamic overprovisioning for data storage systems. In one embodiment, a data storage system can reserve a portion of memory, such as non-volatile solid-state memory, for overprovisioning. Depending on various overprovisioning factors, recovered storage space due to compressing user data can be allocated for storing user data and/or overprovisioning. Utilizing the disclosed dynamic overprovisioning systems and methods can result is more efficient utilization of cache memory, reduction of write amplification, increase in a cache hit rate, and the like. Improved data storage system performance and increased endurance and longevity can thereby be attained.
