摘要：<p>A storage device and a data storage method are provided. The storage device includes a data storage module; a management data storage module for storing the management data information used to manage the data storage module to process the data; an incremental information storage module for storing the incremental information of the management data information generated in a data processing; and a controller for processing the data according to the management data information and updating the incremental information of the management data information and the management data information according to the result of processing the data. The incremental information storage module which uses the non-volatile storage medium combines the management data information which is backed up in the data storage module to resume the management data information stored in the management data storage module when the power is off abnormally. The invention can ensure that the storage device works normally, and improves the reliability of the storage device.</p>
