HGST 10TB SMR HelioSeal HDD – Worlds First 10TB HDD


Setting New Standards in Capacity and TCO
HGST announces the worlds first enterprise-class 10TB HDD for cool-to-cold storage applications. This 10TB drive sets unprecedented capacity leadership at the lowest $/TB and watts/TB by harnessing two complementary technologies: HelioSeal technology and hostmanaged Shingled Magnetic Recording (SMR).


As the first and only company to ship a hermetically sealed, helium-filled HDD, the HelioSeal platform provides the longterm path for delivering the highest capacities, while significantly lowering power and cooling requirements, and improving storage density. To better serve the evolving data centers capacity and efficiency needs, all future HGST enterprise capacity HDDs will be built on the HelioSeal platform.

HGSTs air-based platform has been delivering on the promise of high-capacity, high reliability and performance for decades. However, as the industry continues to push device capacities higher and higher, a transition to helium sealed HDD technology will become essential to achieving these increases while also maintaining reliability.
A Sum Greater than Its Parts:
Foundational Technologies By combining two foundational building blocks, HelioSeal and SMR, HGST is able to deliver unprecedented capacity points at an accelerated rate with very low TCO. This platform enables new storage applications for data that is past its create-and-modify phase of life and is in need of efficient, accessible, long term retention.
