A method and system for wear leveling in a solid state drive by mapping the logical regions of the solid state drive that hold static content or information into the physical regions of the solid state drive that have erase counts more than an average erase count of all of the physical regions. By doing so, it allows the solid state drive to wear level itself naturally through continued usage. In one embodiment of the invention, the erase count of each physical region is incremented with every erasing operation of each physical region. The physical regions that have a high count of erase count operations are mapped with content of the logical regions with static content so that the possibility of future erase operations of these physical regions is reduced.
