In their own words
DriveDx
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.
ValiDrive
ValiDrive is a free Windows utility for quickly spot-checking USB mass storage drives for deliberately missing storage. It tests 576 evenly spaced locations with random data, checking whether each location can store and retrieve information. Before testing a region, it reads the original contents and rewrites them afterward, restoring what was there. The utility detects internal RAM caching and adjusts transfer size when needed to bypass it. A drive map labels each tested location as validated, read error, write error, or no storage. The final report summarizes read and write access times with minimum, maximum, average, median, and variance values. The maker describes this as a quick, cursory check rather than a comprehensive deep test of storage media. While running, it briefly checks for updates through an anonymous DNS query but does not update itself automatically. Listed releases are v1.0.0 from October 6, 2023 and v1.0.1 from October 8, 2023.
