Frequently Asked Questions

Seagate enterprise SAS drives (Exos, Enterprise Capacity) are rated for 2.5M hours MTBF and 550TB/year workload. Standard choice for Dell, HP, and Supermicro servers.

Both are available. Refurbished Seagate SAS drives are typically low-hours datacenter pulls - excellent value for non-critical storage. New drives with full warranty are recommended for production RAID arrays.

RAID 6 is recommended for 12TB SAS drives. Rebuild times are moderate and dual parity protects against the second-drive failure that can occur during lengthy rebuilds.

Use Case Scenarios

🏠
Home & SMB NAS
Building a high-capacity NAS for media, backups and file sharing.
✓ Excellent fit
CMR recording is RAID-safe and fully compatible with Synology, QNAP, TrueNAS and UnRAID. Refurb units offer strong value for non-critical NAS.
💾
Backup Server / Veeam Target
Dedicated backup storage for Veeam, Commvault, or NetBackup.
✓ Excellent fit
12TB SAS drives are ideal for backup targets. Dual-port SAS suits dual-path backup infrastructure.
🏗️
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. SAS dual-port suits HA cluster shared 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. Critical for refurb drives — refuse any with reallocated sectors > 0.
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 6 hours for 12TB. 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 Seagate 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 12TB per drive, budget for replacements before failures occur.

Troubleshooting Guide

Cause: HBA not initialized, SAS expander issue, cable fault, or incompatible controller.
Fix: Verify HBA firmware. Check SAS topology with sas2ircu or StorCLI. Test with known-good cable. Confirm drive is SAS not SATA.
