SSD wear high
A solid-state drive's write-endurance indicator is at or above the configured threshold. This covers both NVMe (percentage-used) and SATA SSDs (Percent_Lifetime_Remain / Wear_Leveling_Count, which Crucible maps into the same percentage-used signal). Plan replacement before the drive enters read-only protection mode at 100%. The rule id stays nvme_wear_high for history; it is not NVMe-only. Use nvme-cli for NVMe devices (/dev/nvmeXnY) and smartctl for SATA SSDs (/dev/sdX); smartctl -a works for both.
