HelioSeal Technology

Introduction - Helium Hard Drive(Disk)

 Data is the ‘life-blood’ of an organization and the key asset that they want to keep around for years. It must be easily accessible, secured, and reliable within an enterprise so it can be processed for real-time use, or analyzed in the future to extract further value or intelligence. It is for these reasons, and others (such as legal, regulatory, due diligence, etc.), why organizations invest in their data. The information extracted can lead to better business decisions, improved organizational processes, advanced technologies, and maximized returns.



As Western Digital develops the head assemblies for its leading helium HDD portfolio, the use of the Damascene process, coupled with energy-assisted magnetic recording technology, will enable the company to deliver even higher HDD capacities in the future, setting standards for others to follow.

Western Digital not only defines the future of hard drives, but has created innovative solutions by making prudent technology choices, investing in multiple parallel technologies, and delivering products to market with exceptional quality and reliability. This disciplined approach to solving industry problems, such as capacity expansion, will evolve the hard drive market for the next decade, and beyond.

Helium-Sealed Technology

The data storage industry is undergoing a major shift in which new market segments and storage tiers are emerging, creating high demand for scalable, mass storage at cost-effective prices. The Capacity Enterprise Hard Drive segment is currently experiencing a 40% compound annual growth rate (CAGR) in petabytes stored.

HelioSeal-based HDDs
Helium-sealed drives are part of this segment and represent one of the most significant storage technology advancements in decades. Western Digital’s heritage in HDD development pioneered heliumsealed drives with the introduction of HelioSeal® technology in 2013 (under the HGST brand).

HelioSeal is the foundational building block for Western Digital’s helium-sealed drive portfolio, with four successful generations of  drives delivered to date, representing a solid and stable field-proven
design. Over 20 million HelioSeal-based HDDs have been shipped to date worldwide





In quick review of the HDD core competencies driven by Western Digital, the company pioneered helium-sealed HDD technology – was the first to deliver multi-stage micro actuation for better head positioning in a data center hard drive – and produced several hard drive innovations using the Damascene head-making process to obtain finer control of the head shape and dimensions when writing to a small, narrow track on disk.
 The decision to improve current core HDD technologies, coupled with the successful development and execution of these technologies, position Western Digital as the leader in hard drives today, and the company that will deliver increased hard drive capacities in the future
