The present application discloses a data writing method, applied to a RAID5 system, comprising: receiving a data writing instruction, and determining a target stripe according to the data writing instruction; determining a first data block in the target stripe and a second data block; calculate a temporary variable according to the original data in the first data block and the original check value in the check block; write the data corresponding to the data write instruction in the first data block For new data, a new check value is calculated according to the new data in the first data block and the temporary variable, and the new check value is written into the check block. The present application can reduce the amplification write coefficient of the storage system and improve the data writing efficiency. The present application also discloses a data writing device, an electronic device 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, an apparatus, an electronic device, and a storage medium. Background technique [0002] In the field of data storage, the efficiency of the system in 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, write amplification is inevitable, that is, the amount of data accessed to the disk will be greater than the amount of data written by the actual user, thus increasing the system processing time. [0003] Therefore, how to reduce the amplification write coefficient of the storage system and improve the data writing efficiency is a technical problem that needs to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0004] The purpose of the present applicat...
