摘要:
A controlling circuit applicable in a physical storage device includes: a dividing circuit coupled to the physical storage device for dividing a storage capacity of the physical storage device into a plurality of divided storage areas, wherein a divided storage capacity of each divided storage area is not larger than the capacity corresponding to the largest address generated by an operating system; and a feedback circuit coupled to the dividing circuit for feeding back the plurality of divided storage areas to the operating system such that the operating system regards the plurality of divided storage areas as a plurality of independent physical storage devices.
摘要:
The present invention provides a method for estimating a capacity usage status of a storage unit, where the storage unit includes a plurality of sectors. The method includes: estimating capacity usage statuses of a portion of sectors; and utilizing a controller to estimate the capacity usage status of the storage unit according to the estimated capacity usage statuses of the portion of sectors in a situation of not estimating capacity usage statuses of all of the sectors of the storage unit.
