Frequently Asked Questions

2 in-stock listings out of 2 tracked; the cheapest is the Seagate 1.2TB 10K SAS 12G 2.5 at $48.00 ($40.00/TB). The table on this page is the live ranking.

Both are in stock: 1 new and 1 recertified or used. The cheapest new is the Seagate 1.2TB 10K SAS 12G 2.5 at $85.00, the cheapest recertified or used the Seagate 1.2TB 10K SAS 12G 2.5 at $48.00 - a 44% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.

None of the 2 tracked listings (including the Seagate 1.2TB 10K SAS 12G 2.5) has a manufacturer-sourced recording value yet, so this page states none - an unsourced drive is never assumed CMR.

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. Refurb units offer strong value for non-critical NAS.
💾
Backup Server / Veeam Target
Dedicated backup storage for Veeam, Commvault, or NetBackup.
✓ Excellent fit
1.2TB 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 1 hours for 1.2TB. 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 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 1.2TB 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.
