Frequently Asked Questions

3 in-stock listings out of 7 tracked; the cheapest is the HP 695842-001 4TB SAS 6G at $68.00 ($17.00/TB). The table on this page is the live ranking.

Both are in stock: 2 new and 1 recertified or used. The cheapest new is the HP 695842-001 4TB SAS 6G at $68.00, the cheapest recertified or used the HP 846523-004 4TB SAS 12G Midline at $120.00. New carries the manufacturer's warranty; recertified a reseller's.

None of the 7 tracked listings (including the HP 695510-B21 4TB SAS 6G) 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. New drives come with full warranty.
💾
Backup Server / Veeam Target
Dedicated backup storage for Veeam, Commvault, or NetBackup.
✓ Excellent fit
4TB 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. Establishes baseline for future comparison.
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 2 hours for 4TB. 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 HP 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 4TB 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.
