Claim Text:
1. In a processor of a storage system, a method for performing storage management operations, the method comprising: determining whether a number of writes to a storage device to store a first data chunk at the storage device is equal to a number of writes to the storage device to store a second data chunk at the storage device; determining a degree to which a sequence of logical block addresses where the first data chunk is stored at the storage device matches a sequence of logical block addresses where the second data chunk is stored at the storage device; determining a degree to which a size of each write of data to store the first data chunk at the storage device matches a size of each write of data to store the second data chunk at the storage device; determining whether or not a write pattern exists based on at least one of the determination of whether the number of writes to store the first data chunk is equal to the number of writes to store the second data chunk, the degree to which the sequence of logical block addresses where the first data chunk is stored matches the sequence of logical block addresses where the second data chunk is stored, or the degree to which the size of each write to store the first data chunk matches the size of each write to store the second data chunk; and performing storage management operations within the storage device based on the determination of whether or not a write pattern exists.
