1. A solid state drive, electrically connected to a host, comprising:

  • a control unit, for receiving data-for-writing from the host, and transforming the data-for-writing to data-for-storage;

    a buffer unit, for storing the data-for-storage;

    a multi-level cell flash memory, electrically connected to the control unit; and

    a voltage detecting unit, for receiving a supply voltage, and issuing an informing signal when the supply voltage is lower than a predetermined voltage, whereinthe control unit proceeds a strong-page programming procedure for storing the data-for-storage to a blank area of the multi-level cell flash memory after receiving the informing signal.
