Key Features and Benefits
Seagate Constellation® ES.2 Hard Drives Review picture 1

  • Industry’s highest capacity enterprise drive for sustaining demanding data growth
  • Fifth-generation, capacity-optimized nearline drive designed for 24x7 enterprise reliability
  • SAS-based, end-to-end data integrity and enhanced error correction for accurate data storage
  • Best-in-class enhanced rotational vibration tolerance ensures consistent bulk data performance
  • Improved power and cooling efficiencies with low power consumption and enhanced PowerChoice™ technology
  • Multi-drive firmware maximized for enterprise system availability
  • Robust performance with dual processor and ramp load technologies
  • Self-Encrypting Drives with FIPS (140-2) certification are government-approved for the U.S. and Canadian governments.**
*Requires TCG-compliant host or controller support. Self-Encrypting Drive (SED) security option (SAS models only) eliminates the need to overwrite or physically destroy drives, enables safe return of drives for warranty or expired lease purposes and allows organizations to securely repurpose or sell hard disk drives. Not available in all models or countries.

**FIPS (140-2) certification is pending.

Energy-Efficient High Capacities
  • Constellation ES.2 drives operate on average at fewer than 12W—the lowest 3TB* drive operating power in the industry. Save up to 54% more by implementing Seagate
  • PowerChoice™ technology’s on-demand idle power savings feature.
  • Maximize data center footprint utilization by supporting up to 114TB per square foot. Reliable Storage Always Available for Your 24x7 World
  • 1.2M hours MTBF and 0.73% AFR deliver the highest level of reliability for a 24x7 capacity optimized drive.
  • Data is stored accurately with SAS-based advanced error correction capabilities.
  • Chassis performance is improved through top-cover attached (TCA) motor design.
  • Best-in-class vibration tolerance ensures consistent, reliable data access and
  • performance in multi-drive systems.

The Seagate Advantage
Built upon leading experience in enterprise storage, the Constellation ES.2 drive maximizes capacity while providing best-in-class features. The Constellation ES.2 drive significantly improves performance with a 6Gb/s interface, the first capacity-optimized drive with 6Gb/s performance in both SAS and SATA interfaces. Improved data security comes from Self-Encrypting Drive (SED) technology based on the AES-256 standard and with FIPS 140-2† solutions that protect data where it lives—on the drive. In addition, the Constellation ES.2 drive carries the Seagate® 5-Year Limited Warranty.

Designed for Your Growing Needs
Ideally suited for use in both server and networked storage bulk-data solutions, the Constellation ES.2 drive offers a host of impressive enterprise features along with a faster, more successful integration experience.

The Constellation ES.2 drive, with its maximum capacity and robust enterprise reliability, provides a sustainable solution for your expanding data storage needs; designed to meet and exceed your expectations, it allows you to come in under power and under budget.

Best-Fit Applications
  • High-capacity bulk-data center storage
  • Mainstream enterprise external storage arrays (SAN, NAS, DAS)
  • Enterprise backup and restore — D2D, virtual tape
  • Centralized surveillance
  • Cloud storage
