status, but also analyzes the changes of all drive health indicators that are closely related to SSD or HDD failures (like SSD wear out / endurance, reallocated bad sectors, offline bad sectors, pending sectors, I/O errors, and more) and alerts the user immediately if anything goes wrong. Unlike most drive utilities, DriveDx not only monitors the drive’s built-in S.M.A.R.T. Don't worry about losing your important data, music, and photographs. Save yourself from data loss and downtime that is associated with unexpected drive failures. DriveDx is an advanced drive-health diagnostic and monitoring utility.
