When the user turns off the power supply, or the power supply In the event of a sudden interruption, the data stored in the memory-type virtual disk still has the risk of being lost. Therefore, the storage security of the memory-type virtual disk technology is still doubted. A large number of access operations, plus when not in use, the internal memory will keep storing data, so the capacitor in the memory will be repeatedly charged for a long time, so the service life of the memory-type virtual disk is also questioned.

In view of the defects existing in the prior art, the applicant conceived the system and method for protecting the data of the volatile recording device of the present invention after careful testing and research, which can overcome the above-mentioned shortcomings of the virtual disk or the volatile recording device, as follows It is a brief description of the present invention.
