HUH721212AL520 – 12TB 7200 RPM SATA 6Gb/s 3.5-Inch Ultrastar Enterprise Hard Drive
The Western Digital Ultrastar HUH721212AL520 is a 12TB enterprise-class 3.5-inch hard drive built on helium-sealed platform technology, aimed at system integrators, data center operators, and storage resellers sourcing capacity drives for enterprise workloads. With a 7200 RPM spindle and SATA 6 Gb/s interface, it fits capacity-oriented enterprise storage arrays and bulk-data applications where per-terabyte cost matters more than the latency of SSDs. Note that sustained performance and power figures in dense enclosures depend on chassis airflow and platform configuration.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | HUH721212AL520 |
| Series | Ultrastar (Western Digital’s enterprise hard drive family) |
| Capacity | 12 TB |
| Interface | SATA 6 Gb/s |
| Form Factor | 3.5-inch |
| Spindle Speed | 7200 RPM |
| Cache | 256 MB |

Good to know
- As a SATA drive, it integrates into a broad range of servers, JBODs, and NAS platforms without requiring SAS host bus adapters — verify backplane and controller compatibility before volume deployment.
- Within the Ultrastar enterprise family, this 7200 RPM SATA model addresses capacity-driven workloads; the helium-sealed design differentiates it from air-filled drives by improving power efficiency and thermal behavior at the 12TB class.
- Confirm firmware requirements and workload expectations (the 550 TB/year rating serves as a sizing guideline) with your integration team before ordering in bulk.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
