US Patent 9355022 Systems and methods for intelligent flash management

Systems and method for performing intelligent flash management are disclosed. A controller may determine if a write pattern exists between a set of writes associated with a first data chunk and a set of writes associated with a second data chunk based on whether a number of writes for first data chunk is equal to a number of writes for second data chunk; a degree to which a sequence of logical block address for the first data chunk matches the sequence of logical block addresses for the second data chunk; and a degree to which a size of each write for the first data chunk matches a size of each write for the second data chunk. The controller may then perform storage management operations based on whether or not a write pattern exists.
