From the developer:
With DriveDx you don't need to worry about losing your important data, music, and photographs.
You can know before your drive is going to fail, because DriveDx tracks more indicators of impending failure than any other product on the market for both SSDs and HDDs.
Regular diagnostic tools simply check the built-in S.M.A.R.T. status of the drive, which provides the user with little information about the actual state of the physical drive.
