Before you buy: this is a SAS drive

SAS drives do not plug into a normal SATA motherboard port. You need a SAS host bus adapter or a backplane that speaks SAS - an LSI/Broadcom HBA in IT mode is the usual answer. A SATA drive will run on a SAS controller, but not the other way round. HBA and IT-mode guide

This is a refurbished or recertified listing

Recertified enterprise drives are pulled from datacentre fleets, tested and resold. They are usually the cheapest route to bulk capacity, and the risk is concentrated in the first weeks - so check SMART data the day it arrives rather than the day you need it.

Frequently Asked Questions

Yes. At our last check it was $548.55 ($34.28 per terabyte at its 16TB capacity), sold renewed under ASIN B098R44KVP. Amazon sets the final price at checkout.

The listing's own title says "renewed" for the ST16000NM002G. That is the seller's claim; we store it verbatim and the warranty is the reseller's, not the manufacturer's. The stored warranty on this row is 5 years, as the listing states it.

Use Case Scenarios

🏠
Home & SMB NAS
Building a high-capacity NAS for media, backups and file sharing.
✓ Excellent 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
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.
