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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
