Abstract: Embodiments of the present invention include a compression system including one or more compressibility inputs; a compression predictor configured to predict the compressibility of data based on the one or more compressibility inputs; a compressor configured to compress the data; and one or more compression inputs. At least one of the compression predictor or the compressor is configured to determine how to compress the data based on the one or more compression inputs. The one or more compressibility inputs comprise at least one of an object extension dictionary, an object signature dictionary, and an entropy estimation algorithm library. The one or more compression inputs comprise at least one of a quality of service profile, a device performance profile and a compression algorithm performance chart.

Abstract: A method for lossy data compression, the method including receiving raw data at a storage device, receiving a request to compress flag, accessing an onboard data compression algorithm library containing various data compression algorithms respectively corresponding to lossy data compression schemes, selecting one of the data compression algorithms based on a number of parameters, running the selected data compression algorithm either online such that the raw data is compressed by the storage device when it is received, and is then stored on the storage device as compressed data, or offline such that the raw data is stored at the storage device, is later compressed by the storage device according to the selected data compression algorithm, and is resaved at the storage device as compressed data.
