STORING DATA BASED ON WRITING FREQUENCY IN DATA STORAGE SYSTEMS

Systems and methods for segregate data in data storage system memory based on writing frequency are disclosed. In some embodiments, infrequently written data is identified and stored in one or more memory regions designated for infrequently written data. Frequently written data is identified and stored in one or more memory regions designated for frequently written data. Garbage collection load can be significantly reduced or eliminated. For example, write amplification of non-volatile solid-state memory is reduced and/or wear of disk heads and other components is reduced. Increased efficiency, longevity, and performance can be obtained.
