Seagate® Exos™ X14 Enterprise Storage: Scalable, Responsive, Innovative.

The Most Scalable Drives in the Datasphere

For everything hyperscale, there’s Exos™ X - the most powerful way to access the datasphere and harness the full potential of the cloud. Exos™ X16, Exos™ X14, Exos™ X12, and Exos™ X10 enterprise hard drives integrate the latest technology in support of a scalable, secure, and reliable cloud data center.* Specifically designed to work in highly scalable environments requiring low power consumption and weight, the Exos™ X series hard drives perform consistently while scaling to meet the stringent TCO requirements of most cloud-based data centers.

* Formerly Enterprise Capacity 3.5 HDD (Helium).

Seagate manufactures hard drives that specifically address the needs of the hyperscale storage market. As the flagship of the Seagate® X class, the Exos™ X14 and Exos X14z enterprise hard drives is the highest-capacity hard drive in the fleet.

Scales to Meet Your Growing Capacity Needs

Seagate Exos™ X14 enterprise hard drives offer the highest rack space efficiency - up to 12.8PB of data in a single 42U rack. Enhanced caching makes it perfect for Big Data applications, providing the fastest hard drive data transfers in the datasphere. Hyperscale SATA models are tuned for large data transfers, providing low latency. You can easily customize your bulk storage requirements with innovative technology advancements (PowerBalance™, PowerChoice™ and RAID Rebuild®). Exos X14 drives help provide low data center TCO, and are architected to offer low power and weight. Simplified infrastructure management is possible with FastFormat™ advanced format feature (4Kn and 512e). Advanced Write Caching helps ensure rapid response rates with a 20% boost in random write performance.1

Innovative Helium Design

The Exos™ X14 hard drive is built on a rock-solid sealed-drive design. A wrought-aluminum base and a helium sealed-drive design with no porosity and uniform density are designed with superior material and wide-weld design for a more robust, hermetically sealed-drive enclosure. Exos™ X14 hard drives incorporate digital environmental sensors for measuring pressure in the drive, helping to ensure high reliability, performance and quality.


Enhanced Enterprise Reliability, Data Protection and Security

Seagate is the industry leader in data-at-rest protection with the broadest offering of technologies to help ensure reliable, trusted products. Seagate Secure™ models provide hardware-based security to help protect data-at-rest. With Instant Secure Erase, drive retirement is safe, affordable, fast and easy. Seagate Secure models meet the NIST 800-88 media sanitization specification and support the Trusted Computer Group (TCG) standard.* The X class Exos™ X14 hard drive is a proven, enterprise-class hard drive with maximum reliability backed by a 2.5 million hour MTBF.
