The WD Purple 1TB WD11PURZ is a 1TB SATA-6G enterprise drive at $165.99/TB - CMR recording makes it safe for all RAID levels and NAS deployments. New unit with full 3-year warranty.
Against every other drive we have an in-stock price for today, this one is cheaper per tb than 0% of them (0 of 243). The cheapest we can currently buy is $14.99/TB; the middle of the market is $37.99/TB.
These are third-party figures about the retail market as a whole, quoted and dated. They are not our own measurements and they do not describe this specific drive.
Resolved against manufacturer compatibility lists we read and dated, capped at 4. Vendor-listed means the manufacturer names this exact part number; fit-verified is our own check of form factor, interface and recording technology against a published requirement. Neither is a guess, and a drive the registry cannot resolve shows nothing here rather than a maybe. How compatibility actually works
Yes. At our last check it was $165.99 ($165.99 per terabyte at its 1TB capacity), sold new under ASIN B0CD2X2MTW. Amazon sets the final price at checkout.
This listing (WD11PURZ, ASIN B0CD2X2MTW) carries no renewed, recertified, refurbished or pulled claim in its title, and Amazon reports it as new. On this site that is what "new" means: sold as factory-new. The stored warranty on this row is 3 years, as the listing states it.
The WD11PURZ's stored recording technology is CMR (manufacturer-sourced), which rebuilds predictably in RAID. The row carries a 180TB/year workload rating.
Use Case Scenarios
🏠
Home & SMB NAS
Building a mid-range NAS for media, backups and file sharing.
~ Good fit
CMR recording is RAID-safe and fully compatible with Synology, QNAP, TrueNAS and UnRAID. New drives come with full warranty.
💾
Backup Server / Veeam Target
Dedicated backup storage for Veeam, Commvault, or NetBackup.
✓ Excellent fit
1TB SATA drives are ideal for backup targets. SATA gives maximum $/TB for backup repositories.
🏗️
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. SATA is fine for single-host VM 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 1 hours for 1TB. 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 WD 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 1TB per drive, budget for replacements before failures occur.
Troubleshooting Guide
Cause: Loose SATA data or power cable, failed port, or drive not spinning up.
Fix: Reseat both cables. Try a different port. Listen for spin-up sound. Test with a known-good cable.
