A method for managing power consumption among a plurality of storage devices is disclosed. A system and a computer program product for managing power consumption among a plurality of storage devices are also disclosed. All the storage devices from among the plurality of storage devices are not powered-on at the same time. A request is received for powering on a storage device. A priority level for the request is determined, and a future power consumption (FPC) of the plurality of storage devices is predicted. The FPC is compared with a threshold. If the threshold is exceeded, a signal is sent to power off a powered-on device. The signal is sent only when the powered-on device is being used for a request with a lower priority than the determined priority. Once, the powered-on device is powered off, the requested storage device is powered on.
