摘要：
A hybrid storage device includes a controller, a volatile storage unit, and a non-volatile storage unit. When the hybrid storage device is in a first working mode, the volatile storage unit is in an enabled state, and the non-volatile storage unit is in a disabled state; when the hybrid storage device is in a second working mode, the non-volatile storage unit is in an enabled state, and the volatile storage unit is in a disabled state. When the hybrid storage device runs in the first working mode, and when detecting that a running parameter of the computer meets a first switching condition, the controller enables the non-volatile storage unit, copies data in the volatile storage unit to the non-volatile storage unit, and switches the hybrid storage device to the second working mode.
