Abstract
An individual adaptive replacement threshold is calculated for each drive of a drive array based on forecasted wear rate, maximum fulfillment time, and wear-life limit. The maximum fulfillment time and wear-life limit are input based on external conditions and design choice. The wear rate for the drive is forecasted using a multiple linear regression/machine learning model in which P/E cycles, POH, WAF, and bytes written are independent variables and wear rate is the dependent variable. The independent variables may be obtained from the drive directly as SMART attributes, or calculated using SMART attributes. The wear-life state of the drive, which is also obtained from the drive directly as, or calculated using, SMART attributes, is compared with the adaptive replacement threshold of the drive. Replacement of the drive is prompted based on the wear-life state of the drive satisfying the adaptive replacement threshold of the drive.
