Detecting Silent SSD Degradation Before Catastrophic Drive Failure
An in-depth look at NVMe wear indicators, reallocated sector counts, and how dewDrive Cloud RMM warns you before drives brick.
Solid-state drives (SSDs) fail differently than traditional spinning hard disks. While mechanical hard disks often exhibit acoustic warning signs, SSDs frequently fail abruptly when NAND flash cells reach endurance exhaustion.
The dewDrive background RMM daemon continuously queries low-level SMART telemetry across SATA and NVMe controllers using isolated diagnostic engines.
Key monitored metrics include: Available Spare Blocks, Percentage Used (Endurance Wear), Media and Data Integrity Errors, and Temperature Spikes.
When an SSD drops below 10% available spare blocks or logs critical error entries, dewDrive immediately triggers proactive alerts via the Web Owner Console and dispatches notification webhooks, ensuring emergency snapshot synchronization before the drive transitions to read-only or catastrophic failure.
