The invention provides a method and device for writing in and reading ephemeral data. The writing-in method includes the following steps that a data writing-in command aiming at a preset storage system is received; whether a target metadata file corresponding to a logical path in the data writing-in command exists in the preset storage system or not is judged; when the target metadata file exists in the preset storage system, according to the target metadata file, an original storage medium where a target ephemeral file is located is determined; whether the original storage hierarchy to which the original storage medium belongs is consistent with a specified storage hierarchy in the data writing command or not is judged, and according to the judged result, the target ephemeral file is processed; data is written in the processed target ephemeral file. The method and device for writing in and reading the ephemeral data can improve the efficiency of writing in and reading the ephemeral data. 本申请提供种临时数据的写入、读取方法及写
