Anecdotal evidence: 2.5&quot; SATA HDD failed for me suddenly just last Tuesday, SMART was fine before, both the attributes and a long (complete surface scan) selftest I did a few weeks ago after I got this lightly used notebook from a colleague (I only needed for tests).<p>I think what people experience is that the sudden death of SSDs doesn&#x27;t occur more often than on HDDs. But with the mechanical issues and slowly building up of bad sectors gone, sudden death is probably the only visible issue left.<p>(Just my personal opinion.)
