Can a drive fail without SMART warnings?

Explanation:
SMART monitoring provides useful health indicators, but it isn’t a guarantee. A drive can fail even if SMART hasn’t warned you, because failures can be sudden or caused by factors that SMART doesn’t reliably detect yet. For example, a sudden mechanical failure, a power or controller issue, firmware bugs, or data-path problems can occur without crossing SMART thresholds. SMART helps you gauge risk over time, but it’s not perfect, so rely on regular backups, redundancy, and proactive replacement as part of a solid storage strategy.
