The invention discloses a flash memory storage device based on cold and hot data analysis technology, the flash memory storage device comprises a main body, a heat dissipation frame, a circulator, a mounting hole and a warning indicator, the top of the main body is provided with a connecting hole, the inner wall of the main body is provided with a rotating shaft, the front side of the main body is provided with the heat dissipation frame, the top of the heat dissipation frame is provided with a temperature detector, and the temperature detector is provided with a temperature sensor. And a warning indicator is mounted on the front surface of the main body. Rapid connection and disassembly can be achieved by installing a connecting hole, when connection is conducted firstly, a connecting block is inserted into the connecting hole, an inclined plate collides with a movable rod, the movable rod returns to the original position under the action of a first spring, the inclined plate is limited, the inclined plate and the connecting block are prevented from sliding off, and the connecting function is achieved; a pressing rod moves to drive a second spring to extend, the pressing rod drives a gear groove to move, a driving gear and a rotating shaft are made to rotate, a cable is tightened to drive a movable rod to contract, and therefore an inclined plate is not limited any more, and the dismounting function is achieved.
