Embodiment Construction

[0072] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0073] First, the terms involved in this application are explained:

[0074] High fault tolerance data: High fault tolerance data refers to images, videos, etc. High fault tolerance data has high fault tolerance, that is, certain bit flip errors are allowed in the data without affecting the user experience.

[0075] In addition, ...

Abstract

The present application provides a data storage method, device, electronic device and storage medium. The method includes: acquiring attribute information of each storage unit in the current storage medium; wherein the attribute information is used to represent the degree of damage of the storage unit; The attribute information of the unit determines the high fault-tolerant unit in the current storage medium; judges whether the data to be stored is high-fault-tolerant data; when the data to be stored is high-fault-tolerant data, the to-be-stored data is stored in the high fault-tolerant unit. The method provided by the above solution extends the usable life of the storage unit by using the severely damaged storage unit as the high fault-tolerant unit and using the high fault-tolerant unit to store the high-fault-tolerant data, thereby prolonging the overall usable life of the storage medium.

Description

technical field [0001] The present application relates to the technical field of storage medium management, and in particular, to a data storage method, apparatus, electronic device, and storage medium. Background technique [0002] With the continuous development of storage technology, the storage density of storage media continues to increase. However, due to hardware characteristics, in a storage medium (such as flash memory, shingled disk, etc.) that cannot be updated in place, the usable life of the storage medium inevitably continues to shorten. Therefore, how to prolong the usable life of the storage medium is an urgent technical problem to be solved. [0003] In the prior art, usually based on a load balancing optimization strategy, the read and write wear of the memory is distributed as evenly as possible to each storage unit, thereby slowing down the depreciation rate of individual storage media. [0004] However, whether the storage medium is usable or not is de...
