A data storage system may store a first data block having a first data configuration generated by a host in a non-volatile memory that is connected to a data module. A data strategy may be generated with the data module in response to the storage of data with the data strategy consisting of at least one trigger associated with identifying the first data block as hot. The first data block can be replicated to a different memory location with a second data configuration as directed by the data strategy with the first data configuration being different than the second data configuration.

Hot data management in a data storage system

Method and apparatus for intelligent caching, protection and transfers of data between a cache and a main memory in a data storage environment, such as but not limited to a solid-state drive (SSD). A main memory (MM) has non-volatile memory (NVM) cells configured for persistent storage of user data. A fast response cache (FRC) has NVM cells configured to provide storage of first data prior to transfer to the MM. A write cache (WC) has NVM cells configured to provide storage of second data prior to transfer to the MM. A controller directs input data to either the FRC or the WC. A first type of error correction encoding (ECC1) is applied to the first data and a different, second type of error correction encoding (ECC2) is applied to the second data. Data may be sent from the FRC to the MM either directly or through the WC.
