Abstract
A caching method and a caching system using dual disks, adapted to an electronic apparatus having a first storage unit and a second storage unit, are provided, in which an access speed of the second storage unit is higher than that of the first storage unit. In the method, a data access to the first storage unit is monitored, a data category of the data in an access address of the data access is identified and whether the data category belongs to a cache category is determined. If the data category belongs to the cache category, an access count of the data in the access address being accessed is accumulated and whether the accumulated access count is over a threshold is determined. If the access count is over the threshold, the data in the access address is cached to the second storage unit.
