Problems solved by technology

In the entire data processing process, the read and write operations of the hard disk are very time-consuming, but when processing user data, write amplification is inevitable, that is, the amount of data accessed to the disk will be greater than the actual amount of data written by the user, thereby increasing the system processing time

Abstract

The invention discloses a data writing method, which is applied to an RAID5 system, and comprises the following steps: receiving a data writing instruction, and determining a target strip according tothe data writing instruction; determining a first data block and a second data block in the target strip; calculating a temporary variable according to the original data in the first data block and the original check value in the check block; and writing new data corresponding to the data writing instruction into the first data block, calculating a new check value according to the new data in thefirst data block and the temporary variable, and writing the new check value into the check block. The method can reduce the amplification writing coefficient of the storage system and improve the data writing efficiency. The invention further discloses a data writing device, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a data writing method and device, an electronic device and a storage medium. Background technique [0002] In the field of data storage, the efficiency of system processing data is a key factor affecting the overall performance of the system. In the entire data processing process, the read and write operations of the hard disk are very time-consuming, but when processing user data, there is inevitably write amplification, that is, the amount of data accessed to the disk will be greater than the actual amount of data written by the user, thereby increasing the system processing time. [0003] Therefore, how to reduce the amplification and writing coefficient of the storage system and improve the data writing efficiency is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of the present a...
