Abstract
A storage system includes a storage medium configured to store data and a buffer memory configured to buffer data to be written to the storage medium. The storage system further includes a controller configured to selectively transfer the buffered data to the storage medium responsive to an invalidity indicator received from an external source. For example, the invalidity indicator may comprise unwrite information received from an external source, e.g., information that indicates that selected buffered data corresponds to deleted file data.
