HUH721212AL520 – 12TB 7200 RPM SATA 6Gb/s 3.5-Inch Ultrastar Enterprise Hard Drive

The HUH721212AL520 is Western Digital’s 12TB helium-sealed enterprise drive, a high-volume SKU frequently sourced by resellers, system integrators, and IT procurement teams for capacity-tier projects. Typical deployment scenarios include enterprise storage arrays, backup and archive targets, and object storage clusters where predictable, sustained throughput is required. Its CMR 7200 RPM design makes it a workhorse for bulk-capacity builds — it complements SSD tiers rather than substituting for them in latency-sensitive roles.

We stock this model for wholesale distribution with batch-consistent supply, which matters for integrators deploying multi-node arrays that require identical firmware revisions and manufacturing dates across all units. Where a single project demands several hundred units, we can coordinate matched-batch allocation to minimize compatibility risk across RAID controllers and storage OS environments.

Procurement & Supply Considerations

• Confirm that target chassis or backplanes support 3.5-inch SATA drives with airflow appropriate for helium-sealed units; manufacturer mounting and cooling guidance applies.
• Ultrastar is WD’s enterprise-class family, positioned above its NAS and surveillance lines — the 550 TB/year workload rating reflects this heavier-duty design point, a common justification in enterprise tenders.
• Before placing volume orders, verify firmware and sector-format compatibility with your RAID controllers or storage OS; enterprise SATA drives can behave differently from desktop SKUs.

All units shipped from our warehouse are enterprise channel stock with full warranty support and a structured RMA process for DOA and failure claims. Export-ready documentation (CE, FCC, RoHS compliance) is available for overseas buyers, and our logistics team supports both consolidated air freight and sea freight depending on order size and delivery schedule. Standard allocation is confirmed at order placement, with lead times communicated upfront so integrators can plan project milestones reliably.

For pricing on volume commitments, matched-batch requirements, or long-term supply agreements, request a wholesale quote and our sales team will respond with current stock levels and tiered pricing.

Wholesale & Procurement Notes

• MOQ negotiable depending on stock availability and project scale.
• Tiered volume pricing available — request a quote for quantities above standard thresholds.
• Typical lead time: 3–7 business days for in-stock allocations; longer for matched-batch or large-volume orders.
• Packing & shipping: anti-static bulk packing or retail-boxed units; air or sea freight, consolidation supported.
• RMA window: DOA claims within 30 days; standard warranty RMA handling per manufacturer terms.
