A method and system for optimizing energy consumption during data file read/write operations in a battery powered disk-based memory system is provided.

DETAILED DESCRIPTION The foregoing and other problems are overcome, and other advantages are realized, in accordance with the presently preferred embodiments of these teachings.
In accordance with one embodiment of the present invention a method for conserving battery power in a battery powered memory device is provided.
The method includes operating the battery powered memory device in a battery-powered mode, and gathering at least one metric associated with retrieving a first data file.
The method also includes operating the battery powered memory device in a non-battery powered mode, wherein operating the battery powered memory device in the non-battery powered mode includes determining a first power efficient location in the battery powered memory device, and storing the first data file in the first power efficient location.
In accordance with another embodiment of the invention a device is provided.
The device includes a memory having a disk-based memory system adapted to optimize power consumption P during data file write/read operations, wherein optimization is based in part on the number of times a data file is expected to be accessed.
In accordance with another embodiment of the invention a method for optimizing battery power is provided.
The method includes analyzing at least one first data file metric associated with a first data file and analyzing at least one second data file metric associated with a second data file.
The method also includes estimating a first and second battery power consumption for memory storage/retrieval of the first and second data file, respectively.
Estimating the first and second battery power consumptions further includes making the first and second battery power consumption estimates based at least partially on the at least one first data file metric and the at least one second data file metric, respectively.
The method includes organizing on a memory device the first and second data files in accordance with the first and second battery power consumption estimates
