Seagate announced it is shipping a 10-terabyte helium-filled hard disk drive for enterprise customers.

The new 3.5-inch hard disk — Seagate’s first such drive — is targeted at the growing storage requirements for private and public cloud-based data centers.

Western Digital, archrival of the Cupertino, Calif.-based Seagate, started shipping its own 10-terabyte hard drive in December. Seagate’s customers for the new drive include Huawei and Alibaba, two of China’s tech giants.

“Cloud-based data center storage needs are expanding faster than many current infrastructures can sustain, rendering the capacity demands of users a herculean task for cloud managers,” said Mark Re, senior vice president and chief technology officer at Seagate, in a statement. “Built on our years of research and development of sealed-drive technology, our new helium-based enterprise drive is designed precisely to help data-centric organizations worldwide solve the needs of their growing storage business.”

The drive is a modern marvel. It has seven platters and 14 heads, and the drive seals in helium to create a quiet, turbulence-free environment, decreasing both friction and resistance on the platters and delivering a low power-per-terabyte ratio. It has 25 percent more density than past drives. Customers from Alibaba and Huawei have said that they can get better storage capacity and lower power usage in the data center.

“At-scale data centers are faced with the challenge of efficiently storing massive amounts of unstructured digital data,” said John Rydning, vice president and analyst at market researcher IDC. “Seagate’s new 10TB HDD for enterprise data centers is its first product to employ helium technology and will help data center customers to expand storage capacity economically.”
