Data caching method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a data caching method and device, electronic equipment and a storage medium, and the method comprises the steps: determining a storage performance demand of the electronic equipment based on the current working state of the electronic equipment; based on the storage performance requirement, determining a multi-level caching strategy for the multiple storage units; wherein different storage units have different storage performances; and performing data caching operation based on the multi-level caching strategies of the various storage units. Thus, dueto the fact that the storage requirements of the electronic equipment in different working states are different, a matched multi-level caching strategy is set for the electronic equipment according tothe working state of the electronic equipment so as to meet the storage performance requirements of the electronic equipment; the problem of storage performance waste or poor storage performance caused by mismatching of storage performance requirements and actually provided storage performance is avoided, erasing P / E cycle abrasion balance of all levels of caches can be balanced, and the problemof cliff type reduction of the storage performance can also be avoided by setting a reasonable multi-level cache strategy.

Description

technical field [0001] The present application relates to computer storage technology, in particular to a data cache method, device, electronic equipment and storage medium. Background technique [0002] With the popularization of smartphones and the high-speed mobile network, mobile devices have become an indispensable tool in life. The storage unit in the mobile device is used to store various data such as photos, videos, documents and other data. However, with the increasing demand of users for storage unit capacity, the flash memory technology in mobile devices has changed from single-level storage single-level cell (Single-Level Cell, SLC) (1bit / cell) to multi-level cell (Multi-Level Cell, MLC) (2bit / cell) to trinary-level cell (Trinary-Level Cell, TLC) (3bit / cell), and even quadruple-level cell (Quad-Level Cell, QLC) (4bit / cell) technology. The storage capacity gradually increases from SLC, MLC, TLC, and QLC, but the performance gradually decreases. [0003] At pres...

Problems solved by technology

But when the SLC storage space is used up, the problem of slow read and write performance of TLC will be displayed, and the read and write performance will show a cliff-like drop, causing the mobile device to freeze.
