摘要：
A data storage system comprises a controller, a first lower performance storage medium and a second higher performance storage medium. The controller is connected to the storage mediums and is arranged to control Input/Output (IO) access to the storage mediums. In operation, the controller is arranged to store an image on the first storage medium, initiate a copy function from the first storage medium to the second storage medium, direct all IO access for the image to the second storage medium, and periodically age data from the second storage medium to the first storage medium.
