Recently, notebook computer has great improvement on its efficiency and battery life along with the ever-changing technology. For example, the clock rate of CPU has dramatically increased from 100MHz to 3800MHz since 1995, 40 times faster than ever. In addition, other components of computer, such as Cache, display chip, Bus, Ram, Device interface, and so on also have astonishing improvement. However, only the development of Hard Disk (HD) is behind schedule no matter for the power consumption or using efficiency. Since 1995, it has only developed 2 to 3 times better than before. During previous years, the technology readiness level of Flash Memory has become better than HD in terms of efficiency and power consumption. Even its controversial prices have substantially dropped with following the increasing level of technology readiness. Moreover, the frequencies of repeated read & write have also improved for its service life which has already reached the mark of over one million frequencies of repeated read & write. Thus, the use of Flash has become an emerging star of storage device after these bottlenecks have been resolved. Therefore, the target of this thesis tends to offer a solution which is able to use the natural advantage of Flash and to mutually combine it with HD in order to make great improvement in HD’s power consumption and using efficiency.
