ENHANCED LOW OVERHEAD DATA PROTECTION IN DATA STORAGE DRIVES

摘要

To provide enhanced operation of data storage devices and systems, various systems, apparatuses, methods, and software are provided herein. In a first example, a data storage device is presented that performs a write process to store data on a storage medium of the data storage device responsive to one or more write operations received over a host interface. The data storage device monitors a quality of the write process and determines when the quality of the write process falls below a threshold quality. Responsive to the quality of the write process falling below the threshold quality, the data storage device indicates the quality of the write process to a data protection node for determination of data parity information that compensates for the quality of the write process, where the data parity information is provided by the data protection node for storage in a selected parity storage device.

1. A data storage device, comprising:
a storage control system configured to:
perform a write process to store data on a storage medium of the data storage device responsive to one or more write operations received from a host system over a host interface;monitor a quality of the write process and determine whether the quality of the write process falls below a threshold quality; andresponsive to the quality of the write process falling below the threshold quality, indicate the quality of the write process to a data protection node for determination of data parity information that compensates for the quality of the write process, wherein the data parity information is provided by the data protection node for storage in a selected parity storage device.
