Abstract
Articles of manufacture and associated methods and systems can be implemented for identifying a condition in which a voltage level being supplied to a data storage device (DSD) may be increased as needed to operate the data storage device. Upon identifying such a condition, the voltage level supplied to the DSD may be increased incrementally. In some implementations, a controller signals a voltage regulator to increment a DSD supply voltage in response to a determination that the present voltage level is insufficient to operate at a desired performance level. The voltage level supplied to a DSD may be adjusted when power is applied to the DSD from an unpowered state, and/or during operation of the DSD. Automatically increasing the voltage supplied to a DSD as needed to support operation may promote high efficiency at low voltages and extended service life at higher voltages.
