Drives do fail, and sometimes spontaneously.
Regardless of how your SSD is rated in DriveDX, it’s always a good idea to backup your Mac with Time Machine or another backup method. Not too bad for nearly 4 years of continuous use! You can further drill down by choosing the “Health Indicators” option from the left sidebar to reveal other indicators of the drives health, including temperature readings, drive reading and write, power cycles, time on, and more.įortunately the soldered in flash memory drives used on modern Macs have a lengthy lifespan, as demonstrated by the screenshots taken for this article, which show a first gen Retina MacBook Air SSD has only used 4% of it’s estimated lifespan according to the Life Percentage Used indicator.
Open DriveDX and you’ll get an overview of the drive, including an overall health rating, SMART status, and lifespan indicator. If you want to continue to use DriveDX past the two week trial, you can pay for it.

Knowing the health of your disk is important for many reasons, but it may be of particular significance now that most modern Macs have SSD drives soldered into the logic board, which means if the SSD is failing, the entire logic board has to get replaced – a much more expensive repair than simply swapping out a drive.
