Expanded data protection with a low additional expenditure in data storage means

摘要

In order to provide improved operation of data storage means and - systems, are herein various systems, devices, a method and software is provided. In a first example is presented to a data storage device, which carries out a read process data on a storage medium of the data storage device in response to a or to store a plurality of write operations, which have been received by means of a host interface. The data storage device monitors a quality of the writing process, and is determined when the quality of the writing process quality falls below a limit value. In response to the fact that the quality of the writing process quality falls below the limit value, shows the data storage device the quality of the writing process, to a data protection node to, of the data parity information for the data determined in order to compensate for the quality of the writing process. The data storage device receives the data parity information and stores the data parity information.
