The Foundational Building Block for High-capacity HDDs

Today’s data centers face many storage challenges—from storage density, to power and cooling costs, to reliability and more. As your data center’s capacity needs grow, your challenges grow as well.

Responding to the complex needs of the modern data
center, Western Digital has developed HelioSeal® technology,
a foundational building block for high-capacity hard disk drives (HDDs). This innovative technology hermetically seals the HDD and replaces the air inside with helium, which is one-seventh the density of air. The less-dense atmosphere resets the boundaries and challenges of conventional high-capacity HDDs, allowing for dramatic increases in efficiency, reliability and value.

HelioSeal technology complements magnetic recording technologies like shingled magnetic recording (SMR), microwave-assisted magnetic recording (MAMR), heat-assisted magnetic recording (HAMR) and bit-patterned media (BPM). When paired with SMR, HelioSeal technology will enable the fast-growing sequential workload storage market.

The Science of HelioSeal®

The benefits of helium are well known. For over a decade, the HDD industry has looked for solutions to lever-
age helium. However, no one has been able to manage leakage, nor establish a development process that can cost-effectively manufacture millions of these drives. After six years of design and rigorous testing, Western Digital successfully patented the first helium development process; HelioSeal technology. In 2013, we raised the standard for storage efficiency, reliability and value by shipping the first helium HDD, the Ultrastar® He6, using our patented production process.

Proven Reliability

Reliability has always been a Western Digital hallmark. Prior to shipping helium-filled drives, we performed long- term reliability testing, with 5,000 drives each running more than 1,000 hours (over 5 million combined hours), showing no seal degradation on any of the drives.

Western Digital helium drives undergo accelerated stress testing, including high-temperature soaking, thermal cycling, pressure cycling, humidity cycling and shock testing. Every drive is tested for seal integrity during the manufacturing process prior to shipping. Additionally, our helium drives utilize internal environmental telemetry to monitor seal integrity and report any potential issues.

Our Ultrastar DC HC500 Series of HelioSeal drives continues to push capacity and limits in our fifth generation 14TB Ultrastar DC HC530 HDD. Our HelioSeal platform quality proved so successful in the field that we increased the reliability rating by 25% to 2.5M hours MTBF compared to enterprise-class air-filled drives.

Driving Down TCO: The Value of HelioSeal® Technology

HelioSeal technology delivers today’s lowest total cost of ownership (TCO) for hyperscaleand data-centric applications.

Unmatched storage density with 14TB capacity in an eight-disk design and a 3.5-inch HDD footprint. That’s 75% more storage capacity for mainstream applications than 8TB air-based drives, saving you rack space.

Greater power efficiency with 27% lower operating power than Ultrastar 8TB air drives. Our 14TB HelioSeal drives consume just 5.6 watts during idle operation, a 56% reduction in watts-per-TB compared to Ultrastar air-based HDDs.

Lower cooling requirements with drives that typically run 4 ̊- 5 ̊C cooler to lower power and cooling cost. Cooler operation also results in better reliability and enables systems with higher storage densities.

Quieter operation and up to 45% lower weight-per- TB than 8TB Ultrastar drives improve environmental conditions in high-density deployments and enable more storage capacity where building codes enforce floor loading limits.

More affordable than ever with the introduction of our high-volume, fifth-generation 14TB HelioSeal HDD— higher volume leads to lower cost to the market.
