Exos EnterpriseOverview:

Scalable. Responsive. Innovative.

Seagate manufactures hard drives that specifically address the needs of the hyperscale storage market. As the highest-performing hard drive in the Seagate® X class, the Exos® 2X14 enterprise dualactuator hard drive utilizes MACH.2™ technology enabling up to 2x the performance of an enterprise single-actuator 3.5-inch hard drive.

Best-Fit Applications

  • Hyperscale applications/cloud data centers
  • Massive scale-out data centers
  • Big data applications
  • Content delivery networks
  • Mainstream enterprise external storage arrays
  • Distributed file systems, including Hadoop and Ceph
  • Enterprise backup and restore-D2D, virtual tape
  • Centralized surveillance
  • High-bandwidth streaming applications


Highest Performance for Highest Rack Space Efficiency

MACH.2 technology enables up to 2x the performance of an enterprise singleactuator 3.5-inch hard drive1

Highest 14TB hard drive performance, making it the logical choice for cloud data center and massive scale-out data center applications

14TB of capacity available as two independently addressable, 7TB logical units

PowerBalance™ feature optimizes IOPS/Watt

Helium sealed-drive design delivers lower total cost of ownership through lower power and weight

Next-generation helium side-sealed weld technology for added handling robustness and leak protection

Digital environmental sensors to monitor internal drive conditions for optimal operation and performance

Latest hermetic interconnect technology supporting higher data rate heads and higher pin counts for extreme thermal conditions

Proven enterprise-class reliability backed by 5-year limited warranty and 2.5M-hr MTBF rating
