I had some SSDs which reported that they have reached the maximum amount of data that may be written.

I have replaced them promptly, without waiting to see if they will really die.

I also had some new HDDs which have failed the SMART self-tests, so I was able to request replacements. After having once problems with a new HDD, I have always run all the SMART self-tests on all new HDDs, before storing any valuable data on them, and that has proved to be a good policy.
