Failure predictability is not inherently higher for HDDs than for other disk technologies. While HDDs are mechanical and can show wear patterns that SMART telemetry might hint at—such as rising reallocated sectors or increasing error rates—these signals are not a guaranteed warning and some drives fail suddenly without clear precursors. Other technologies, like SSDs, have their own predictable wear-out mechanisms tied to write endurance, but they can also fail unexpectedly due to controller or firmware issues. Because you can’t reliably claim that one technology is consistently more predictable than another, the statement is not true. Also, failures aren’t always detectable in advance, and they certainly don’t never fail.
