  • Patent number: 9606750
    Abstract: A method of storing data in a distributed manner based on data compression ratio prediction, and a mass storage device and system using the method are disclosed. The device includes a compression ratio predicting unit, a compressing unit, and a control unit. When an address and first unit sized data are received, the compression ratio predicting unit estimates the predicted compression ratio of the first unit sized data. The compressing unit generates compressed data. The control unit calculates the benefit of compression based on at least the estimated predicted compression ratio, stores the compressed data in a first storage area if the calculated benefit of compression is higher than a predetermined benefit threshold value, and stores the first unit sized data in the second storage area if the calculated benefit of compression is equal to or lower than the predetermined benefit threshold value.
