A voltage adjustment circuit for a storage medium includes a storage medium interface, a storage medium control chip, and a switch module. When the storage medium is read or written to by the storage medium control chip, the storage medium control chip transmits a pair of differential signals to the storage medium interface so that the switch module can control a power supply to power the storage medium. And the switch module will control the power supply not to power the storage medium when the storage medium control chip does not operate to read or write the storage medium.
