Our Verdict

Best for

Mac users who want early warning of a failing SSD or HDD before data loss.

Skip if

You're on Windows, or you need active drive repair rather than health monitoring.

What is DriveDx?

DriveDx is a macOS utility that continuously analyzes S.M.A.R.T. attributes and other health indicators for internal and external hard drives and SSDs, flagging each drive as OK, Failing, or Failed. The goal is to surface early warning signs of drive failure while there's still time to back up data, rather than discovering a dead drive after the fact. It runs background monitoring with desktop alerts, offers short and extended self-tests, and calculates separate health and performance ratings using algorithms tuned differently for SSDs versus traditional HDDs. It also supports scheduled email reports for remote or headless Mac monitoring.
