Active@ Hard Disk Monitor vs DriveDx

Active@ Hard Disk Monitor checks disk health on Windows with S.M.A.R.T. monitoring and surface scans for bad sectors. It can monitor disk performance and state in the background, including when launched at Windows startup. Temperature tools record history, draw graphs, and show the current disk temperature in the system tray. When critical conditions appear, the software can send email or popup notifications. It also creates event logs and S.M.A.R.T. reports containing disk activity information over time. The Pro version adds remote monitoring: it can display disk information and receive notifications from remote computers on a local or global network. Pro also provides temperature graphs across a day, week, month, or specified period. The Freeware plan costs nothing and is for personal use only. Professional is intended for business purposes and can monitor up to 3 PCs remotely; its general license covers personal and commercial use, while its enterprise license is for company offices and branches worldwide. The site lists version 26.0.1, dated February 1, 2026, as a maintenance release.

DriveDx monitors and diagnoses SSD and HDD health on macOS, with the aim of helping users identify drive trouble before data loss or downtime. It evaluates indicators such as SSD wear and write endurance, I/O errors, pending sectors, and reallocated bad sectors. Its reports distinguish Warning, Failing (Pre-fail), and Failed states. The app can run in the background, check drives periodically, and alert users when it detects an issue. Users can initiate and control self-tests of electrical or mechanical performance and read performance. DriveDx calculates health and performance ratings, plus an indicator of remaining SSD lifetime. It can email problem alerts and drive status reports, with reporting configurable by criteria, and can alert users when free space crosses a chosen threshold. The product page lists compatibility from macOS 10.9 through macOS 26 and invites users to try it free, without specifying a trial length. There is no free plan. The personal license costs $19.99 as a one-time purchase for up to three personal computers and non-commercial use; other licenses cover household or commercial computer counts.
