Abstract
A computer-implemented method for efficient data storage is provided. A first storage medium associates data stored on one or more data storage media with a unique identification value (ID) for the purpose of determining de-duplication status of the data. In response to receiving a request to read the data from a logical address, the first storage medium retrieves the data from a second storage medium based on the unique ID. In response to receiving a request to write the data to a logical address, the one or more data storage media store at least one copy of the data based on the de-duplication status of the data.
