There is some reasonable data already on one or two year failure rates of SSDs, so it is absurd to give any credibility to the kind of anecdotal evidence the article mentions.
It absolutely should NOT be given credence. Anecdotal evidence is useless, or worse than useless, when looking at reliability. A careful statistical study with good methodology is required.
The problem with anecdotal evidence is that there are millions of SSDs in use. Even if the annual failure rate is only 0.1%, there should be thousands of SSDs failing each year. All anecdotal evidence tells us is that there are indeed failures -- it gives us no useful information on the failure rate. The useful information that anecdotal evidence might provide is failure modes and how companies deal with warranties. But the referenced article provides nothing like that.
