Hard disk in-depth online analysis

SpeedFan offers a feature named "in-depth online analysis" that compares the hard disk's S.M.A.R.T. data to a database with statistical models of hard disks allowing early detection of potentially degraded hard disks. Messages inform the user of specific situations and problems, which Almico says is “as if a human expert had looked at the data”.
