It has been discovered by the inventors that the efficiency and data integrity of a storage device can be improved by dynamically adjusting certain operating parameters to optimal values during the operation of the storage device. In one embodiment, the physical properties of a storage device such as a hard disk drive are measured during the manufacturing process to determine the dependency of the storage device upon the environmental conditions in which the storage device is operating. The physical properties of the storage device and the effect the operating environment of the storage device has upon the storage device performance are determined, and optimal values for the write current of the storage device are stored in a lookup table. The temperature in which the storage device is operating is used as a reference into the data that resides in the lookup table. Optimal values for the precompensation delay may also be stored in the lookup table. During operation of the storage device, the temperature of the operating environment is sensed and used as a reference value into the lookup table. The optimal values of write current and precompensation delay corresponding to the sensed temperature are retrieved, and the write current and precompensation delay of the storage device are adjusted accordingly.
