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.

Currently only refurbished units are available. These are datacenter pulls with low power-on hours. Verify SMART data on arrival and look for sellers with 90+ day warranty.

RAID 6 is strongly recommended for 16TB SAS drives. At this capacity, RAID 5 rebuild times exceed 24 hours - too risky for a single parity stripe. Use RAID 6 or RAID 60 for arrays of 12+ drives.

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
16TB SAS drives are ideal for backup targets. Dual-port SAS suits dual-path backup infrastructure.
☁️
Object Storage / Cold Data Tier
High-density storage for MinIO, Ceph or Hadoop at scale.
✓ Excellent fit
At 16TB per drive, a 60-bay JBOD delivers 960TB raw — enough for petabyte-scale object storage.

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 8 hours for 16TB. 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 16TB 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.
