<P>PROBLEM TO BE SOLVED: To properly restart data optimization processing even if data optimization processing is suspended under situations where calculation resources can be not fully used. <P>SOLUTION: In a data storage device, even if data optimization processing is suspended, a data difference quantity for data updates from the time of suspension is used to determine proper restarting of the optimization processing, and thus the data storage device can efficiently perform optimization processing and is excellent in response performance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
