Frequently Asked Questions

4 in-stock listings out of 4 tracked; the cheapest is the Dell M40TH 8TB SAS 12G 512E at $245.00 ($30.63/TB). The table on this page is the live ranking.

Both are in stock: 2 new and 2 recertified or used. The cheapest new is the Dell M40TH 8TB SAS 12G 512E at $360.00, the cheapest recertified or used the Dell M40TH 8TB SAS 12G 512E at $245.00 - a 32% 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 4 tracked listings (including the Dell M40TH 8TB SAS 12G 512E) 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.

✓ 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

8TB 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 4 hours for 8TB. 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 Dell 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 8TB 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.
