A method, non-transitory computer readable medium, and device that assists with proactive prediction of disk failure in a RAID group includes obtaining performance data for a plurality of storage drives. The obtained performance data is compared with a stored classification data to predict one or more storage drives of the plurality of storage drives failing within a time period. The data present in the one or more storage drives predicted to fail based on the comparison is copied on to one or more secondary storage drives. A notification including a list of the one or more storage drives predicted to fail is sent upon the copying the data on to the one or more secondary storage drives.
