A method to speed up access to an external storage device for accessing to the external storage device comprises the steps of:(a) during startup of a computer, setting up part of a physical memory of the computer as a cache memory for use by the external storage device, in the form of a continuous physical memory area outside the physical memory area that is managed by an operating system of the computer;(b) upon detection of a request to write data to the external storage device, writing the data to the cache memory; and(c) sending the data written in the cache memory to the external storage device to be saved therein.
