Abstract: A hard drive energy-saving control method is disclosed. The method includes: obtaining a historical working state of a hard drive in each preset time segment, where each preset time segment is each preset time segment in at least one statistic period; predicting a working state of the hard drive in a next time segment of the current time segment according to the historical working state of the hard drive; and selecting a corresponding energy-saving policy level according to the working state of the hard drive in the next time segment, and performing energy-saving control on the hard drive. Embodiments of the present invention solve the technical problem in the prior art that energy consumption of a hard drive is not correlated with actual service access traffic and the energy-saving efficiency is not optimum. The embodiments of the present invention improve the energy-saving efficiency of the hard drive.
