The present disclosure provides a system and method for wear leveling. In one example, the method includes receiving first data to be stored to a first data storage medium and storing the first data to a first storage location in a nonvolatile data store of a second data storage medium comprising a solid-state memory. The method also includes setting a pointer to enable writing second data that is received to a next storage location in the nonvolatile data store. The next storage location comprises an address of the nonvolatile data store that is sequentially after an address of the first storage location. When the address of the first storage location is a last addressed location of the nonvolatile data store the pointer is set to enable writing the second data to a first addressed location of the nonvolatile data store. The method also includes writing the first data stored in the nonvolatile data store to the first data storage medium when a trigger occurs and preserving the pointer during the writing from the nonvolatile data store to the first data storage device such that the pointer enables writing the second data to the next storage location.

System and method for wear leveling in a data storage device

A bus-connected device includes a data storage element, a physical layer and a controller. The data storage element stores user data and multiple adaptations for multiple platform protocols. The physical layer uses at least a portion of a selected one of the multiple platform protocols to access the user data. The controller controls and communicates with the data storage element using a controller communication protocol that is neutral relative to the multiple platform protocols.
