Management method and system of data storage device and data storage device

The invention discloses a management method and system of data storage equipment and the data storage equipment, and belongs to the technical field of storage. The management method of the data storage device comprises the following steps that a mapping table block and a data block are configured in the data storage device, a mapping table is stored in the mapping table block, and write-in data is stored in the data block; when a new flash memory block storage mapping table needs to be configured, selecting a first flash memory block with the minimum erasure frequency in the mapping table block and a second flash memory block with the minimum erasure frequency in the data block; and selecting the flash memory block with the minimum erasing frequency from the first flash memory block and the second flash memory block, and writing the mapping table. By means of the management method of the data storage device, the service life of the data storage device can be prolonged. 本发明公开了一种数据存储设备的管理方法、系统及数据存储设备，属于存储技术领域。所
