Data storage method and system

The invention provides a data storage method. The method comprises the steps that an electronic device obtains a data storage task, wherein the data storage task comprises a designated address for storing target data outside the electronic device into the electronic device; and under the condition that the designated address points to a first nonvolatile storage device of the electronic device, the target data is stored into a second nonvolatile storage device of the electronic device responding to the data storage task, wherein the writing speed of the first nonvolatile storage device of the electronic device is smaller than that of the second nonvolatile storage device of the electronic device. The invention furthermore provides a data storage system and a computer readable storage medium. 本公开提供了种数据存储方法，包括：电子设备获得数据存储任务，所述数据存储任务包括将所述电子设备外的目标数据存储到所述电子设备的指定地址；在所述指定地址指向所述电子设备的第非易失性存储设备的情况下，响应于所述数据存储任务，将所述目标数据存储到电子设备的第二非易失性存储设备；其中，所述电子设备的第非易失性存储设备的写入速度小于所述电子设备的第二非易失性存储设备。本公开还提供了种数据存储系统以及种计算机可读存储介质。
