HGST Ultrastar He12 12TB SATA Data Center Hard Drive with Fourth-Generation HelioSeal Helium Technology, PMR Recording, 7200 RPM, 256 MB Buffer, and 2.5 Million Hour MTBF for Enterprise Storage and Server Deployments
The Western Digital HGST Ultrastar He12 HUH721212ALE600 (0F30144) is a 12TB helium-filled enterprise SATA hard drive that delivers 7200 RPM performance, 256 MB buffer, and Perpendicular Magnetic Recording (PMR) technology in a standard 3.5-inch form factor for 24/7 data center and server environments. The He12 uses fourth-generation HelioSeal helium technology with an 8-disk design that increases capacity by 20% over prior 7-disk designs while reducing internal turbulence, power consumption, and operating temperature for dense multi-drive enclosures.
Built on the same platform that powers thousands of data center and hyperscale storage deployments worldwide, the Ultrastar He12 achieves a 2.5 million hour MTBF rating and handles sustained workloads up to 550TB per year. The SATA/600 interface provides broad compatibility with server, NAS, and JBOD storage platforms, while the sealed helium environment delivers a lower power profile per terabyte than air-filled enterprise drives. The 3.5-inch form factor at 1.46 lb fits standard server drive bays and storage enclosures with no adapter required.
Where the HGST Ultrastar He12 12TB Fits
- Enterprise servers and storage arrays requiring high-capacity SATA drives where the 12TB capacity with 550TB/year workload rating handles sustained read/write operations across 24/7 multi-user environments, the SATA/600 interface provides drop-in compatibility with existing server and storage infrastructure, and the 2.5 million hour MTBF delivers predictable reliability for large drive fleet management
- Dense multi-drive JBOD and NAS enclosures where the fourth-generation HelioSeal helium technology provides lower power consumption and reduced vibration per drive compared to air-filled alternatives, the 8-disk design maximizes capacity per drive bay, and the sealed helium environment maintains consistent performance across temperature and altitude variations
- Cloud, hyperscale, and bulk storage tiers where the 12TB SATA capacity provides cost-effective density for cold storage, archive, and content delivery workloads, the PMR recording technology provides proven field reliability without requiring new controller firmware, and the Ultrastar platform enables rapid qualification into existing infrastructure
