Patent attributes
Predicting individual drive failures is achieved using machine learning models of drive behavior history based on samples of SMART data attributes collected over distinct time-periods. The drive behavior history is a historical feature added to drive features modeled based on a last sample of SMART data attributes. The drive behavior history feature is used in successive modeling of drive behavior history to increase accuracy in predicting an individual drive's failure over time. Consecutive individual drive failure predictions are aggregated to further increase accuracy in predicting an individual drive's failure. In one embodiment, the system models drive behavior history and other drive features using a machine learning model. Individual drives classified as predicted to fail within a certain period of time are incorporated into a drive replacement strategy that factors in a field-based replacement cost associated with the drive.
