Abstract
A device comprises a first storage media and a controller. The controller configured to generate a first operational metric using a first set of operational data at a first frequency and a second operational metric a second set of operational data at a second frequency different than the first frequency; receive a write command to write data to the first storage media; and divert the write command to write data to a second storage media instead of the first storage media when at least one of the first operational metric and the second operational metric indicates that writing data to the first storage media may be harmful to the magnetic rotating disk or result in data loss.
