Use Case Scenarios

🏠
Home & SMB NAS
Building a mid-range NAS for media, backups and file sharing.
~ Good fit
Verify CMR recording before using in RAID. New drives come with full warranty.
💾
Backup Server / Veeam Target
Dedicated backup storage for Veeam, Commvault, or NetBackup.
✓ Excellent fit
2TB SATA drives are ideal for backup targets. SATA gives maximum $/TB for backup repositories.
🏗️
Virtualization Host Storage
VM images and snapshots on Proxmox, VMware or Hyper-V.
~ Good fit
Suitable for VM storage where workloads are not IOPS-intensive. SATA is fine for single-host VM storage. Consider NVMe cache for latency-sensitive VMs.

Maintenance & Troubleshooting

Maintenance Checklist

On installCheck SMART baseline on arrival
Run smartctl -a /dev/sdX and record: Reallocated_Sector_Ct, Power_On_Hours, Spin_Retry_Count. Establishes baseline for future comparison.
MonthlyRun SMART short self-test
smartctl -t short /dev/sdX — takes 1-2 minutes, catches most developing issues. Schedule during off-peak.
QuarterlyRun SMART long self-test
smartctl -t long /dev/sdX — full surface scan, takes 1 hours for 2TB. Any test failure is grounds for immediate replacement.
QuarterlyCheck RAID array health
Verify no degraded drives. A degraded array with no hot spare is one failure from data loss. Check mdstat or controller UI.
AnnuallyVerify drive firmware version
Check WD support site for firmware updates. Some versions have known bugs affecting integrity.
Every 3-5 yearsPlan proactive replacement
Enterprise HDDs have higher failure rates after year 4-5. At 2TB per drive, budget for replacements before failures occur.

Troubleshooting Guide

Cause: Loose SATA data or power cable, failed port, or drive not spinning up.
Fix: Reseat both cables. Try a different port. Listen for spin-up sound. Test with a known-good cable.
