Beyond Surface Metrics: Comprehensive Hardware Auditing for Enterprise SAS Drives

The article addresses a critical supply chain vulnerability: enterprise disks labeled 'new' may actually be refurbished or high-cycle components. SMART data alone is insufficient because RAID controllers abstract disk telemetry at different layers—you must verify at the correct layer to detect discrepancies. This matters because deploying unverified drives into production storage pools can create latent failure modes that cascade years later, making pre-deployment auditing essential operational practice.
