A method of garbage data storage device and

Example embodiments provide a method and apparatus for garbage data storage according to the invention, the first data are recorded in each segment within the data amount of the first data storage device current time and the time before the current time is set in advance the amount of change; calculating a predicted value of the first data according to the change of the amount of data within each segment of the first data and the first data; prediction of the first data according to each segment value determining junk data segment needs to be recovered, and more garbage lower priority segment waste generated recovery rate, thereby improving the efficiency of garbage data.
