Modification-frequency-based tiered data storage and garbage collection system
A modification-frequency-based tiered data storage garbage collection system includes a storage device coupled to a host engine. The storage device includes a data storage and garbage collection engine and storage subsystems. The data storage and garbage collection engine receives first modified data from the host engine that provides a modification to first current data stored in a first data storage element provided by one of the storage subsystems and grouped in a first superblock associated with a first data modification frequency range. The data storage and garbage collection engine then determines a first frequency of modification of the first current data and, based on that, writes the first modified data to a second data storage element provided by one of the storage subsystems and grouped in a second superblock associated with a second data modification frequency range that is different than the first data modification frequency range.
