Data storage device

The utility model provides a data storage device, relates to the technical field of engineering data storage, and aims to solve the problems that files are put in a file cabinet in order, so that corresponding workers are inconvenient to find the files, the files are easy to be disordered, and each worker has an independent file cabinet and is inconvenient to monitor and manage. An upper row of drying boxes and a lower row of drying boxes which are uniformly spaced are fixedly mounted on the front end surface of the storage rack body; corresponding storage boxes are vertically mounted below the drying boxes in a sliding manner; and a sealing plate is fixedly butted to the front lower side of the front end edge of the drying box in an inclined manner. When the storage box moves downwards, the lug columns slide in the stroke holes, at the moment, the upper end opening of the storage box is separated from the sealing plate, data can be taken and placed in the storage box conveniently and quickly, and the data ca
