Its goal is to find, test, diagnose, and repair hard disk drive problems, report, and display S.S.D. and HDD health, performance degradations, and failures. Hard Disk Sentinel gives complete textual description tips and displays/reports the most comprehensive information about the complex and solid-state disks inside the computer or external enclosures (USB / e-SATA). Many different alerts and report options are available to ensure the maximum safety of your valuable data.

The software monitors hard disk drive / HDD status, including health, temperature, and all S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology, built in most hard disks, solid-state disks, and hybrid drives (S.S.H.D.) today) values for each disk. Also, it measures the disk transfer speed in real-time, which can be used as a benchmark or to detect possible hard disk failure performance degradations.
