Abstract: A method for controlling the data flow in the storage device is applied to a host, and includes obtaining a cache input and output parameter, determining whether the cache input and output parameter meets an overload condition, when the cache input and output parameter meets the overload condition, obtaining a first bandwidth value, where the first bandwidth value is less than a current flushing bandwidth value of the cache, determining a quantity of tokens based on the first bandwidth value, and controlling the data flow in the storage device.
