Understanding SMART Attributes
+
+ SMART (Self-Monitoring, Analysis and Reporting Technology) attributes are sensors built into hard drives and SSDs.
+ Each attribute has a current value, a worst recorded value, and a threshold. When the current value drops below the threshold,
+ the attribute is considered failed. Values typically decrease from 100 (or 200/253 on some drives) as the attribute degrades.

About Self-Tests
+
+
+ Short Test (~2 minutes): Performs a quick check of the disk's
+ basic functionality including read/seek tests on a small portion of the disk surface.
+
+
+ Extended Test (hours): Performs a comprehensive surface scan
+ of the entire disk. Duration depends on disk size - typically 1-2 hours per TB.

Best Practices
+
+ -
+
+ Run a short SMART test monthly to catch early issues
+
+ -
+
+ Run an extended test quarterly for comprehensive verification
+
+ -
+
+ Maintain regular backups - SMART can detect some failures but not all
+
+ -
+
+ Keep disk temperatures below 50°C for optimal lifespan
+
+ -
+
+ Replace disks proactively after 4-5 years of heavy use
