Re: "SSDs fail at an alarming rate in space"
Hard drives, even with the best SMART monitoring in the world, fail unpredictably a large portion of the time. Any large hard drive survey will show you that.
And sometimes they fail so quickly even WITH SMART monitoring that you don't stand a chance of being able to do anything about it.
Reporting bad-sectors may be a symptom of imminent failure, but only so far as coughing up your lungs is a symptom of death. There are many other ways to die without doing that.
