  • Limiting access operations in a data storage device
    Patent number: 10534716
    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 hybrid data storage device is configured to limit write operations on the one or more data storage caches to less than an endurance value for the data storage cache. In one implementation, the data storage cache management sub-system limits or denies requests for promotion of data from the main data store to the one or more data storage caches. In another implementation, the data storage cache management sub-system limits garbage collection operations on the data storage cache.
    Type: Grant

  • Cache over-provisioning in a data storage device
    Patent number: 9842060
    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.
