Seagate Exos X14 3.5-Inch Internal 512e/4Kn SATA Enterprise Hard Drive
Perfect for storage-intensive workloads, OLTP, Hadoop, Ceph and HPC applications

Overview:

Scalable. Responsive. Innovative.

For everything hyperscale, there’s ExosTM 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.

Exos X14 Series

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 are the highest-capacity hard drives in the fleet.
