Embodiment Construction

[0041] The present invention proposes a first embodiment to provide a storage medium protection method. In storage devices that include different types of storage media, the number of erasable times and / or utilization rates of the storage media are different, which makes the storage device underutilized; The embodiment of the present invention provides a physical block with the least number of erasing and writing for data storage, so that the physical block is fully utilized, and the service life of the storage device is maximized.

[0042] See figure 1 , The protection method of this embodiment is applied to a storage device that includes several different types of storage media, and the steps include:

[0043] Step S10, unify the structure and information of the storage medium;

[0044] Step S11, divide logical blocks; it is convenient to find the physical block with the least number of erasing and writing;

[0045] Step S12, providing the physical block with the least number o...

Abstract

The invention discloses a method and a device for protecting storage medium. The method for protecting storage medium is applied to storage equipment comprising a plurality of different storage media and comprises the following steps: unifying the structure of the storage medium and management of information; dividing logic blocks for conveniently searching a physical block with the least erasing times; and providing the physical block with the least erasing times to store data. The method and the device for protecting storage medium achieve the purpose of protecting the storage medium in the device through providing the physical block which accords with the requirement and has the least erasing times for data storage.

Description

Technical field [0001] The present invention relates to the field of storage media, and in particular to a method and device for protecting storage media. Background technique [0002] With the development of flash memory technology, there are more and more types of flash memory media. In the prior art, in order to achieve a certain special purpose, different types of flash memory media are applied to the same flash memory device. However, the existing flash memory device protection method for flash memory media can only be adapted to the situation where there is only one kind of flash memory media, and cannot be adapted to multiple flash media at the same time, so it can no longer be applied to the above flash memory devices including multiple flash media. Summary of the invention [0003] One of the objectives of the present invention is to provide a storage medium protection method and device to maximize the service life of the storage device. [0004] The present invention p...
