Abstract

A hybrid data storage device disclosed herein includes a main data store, one or more data storage caches, and a data storage cache management sub-system. The data storage cache may be divided into an over-provisioned portion and an advertised space portion. Clusters of data on the data storage cache corresponding to the over-provisioned portion are marked as pending eviction rather than actually evicted when the data storage cache management sub-system receives a write request, thereby increasing the effective capacity and reducing write amplification of the data storage cache.
