Data writing method, device, electronic equipment and storage medium

The embodiment of the invention discloses a data writing method, a device, electronic equipment and a storage medium. The method comprises the steps: judging whether the size of to-be-stored data reaches the data capacity of a storage block or not when a data writing instruction is received; if the size of the to-be-stored data reaches the data capacity of one storage block, performing writing operation on the to-be-stored data by taking the storage block as a mapping unit; If the size of the to-be-stored data does not reach the data capacity of one storage block, performing writing operationon the to-be-stored data by taking the storage page as a mapping unit. By adopting the technical scheme, the utilization rate of the storage space is improved, and redundant data is reduced. 本发明实施例公开了一种数据写入方法、装置、电子设备及存储介质，所述方法包括：当接收到数据写入指令时，判断待存储数据的大小是否达到一个存储块的数据容量；若待存储数据的大小达到一个存储块的数据容量，则以存储块为映射单元对所述待存储数据进行写入操作；若待存储数据的大小没有达到一个存储块的数据容量，则以存储页为映射单元对所述待存储数据进行写入操作。通过采用上述技术方案，提高了存储空间的利用率，减少了冗余数据。
