Constellation ES drives offer the world’s highest capacity at 2TB while providing enterprise robustness for Tier 2/nearline environments. They are differentiated from 3.5-inch desktop drives by offering enterprise-class reliability and superior data integrity with a UER of 1E10-15. Enterprise-class rotational vibration tolerance provides robust protection from chassis and fan vibrations (RV 12.5 rad/sec 20 to 1500Hz). The drives are offered with either a 3-Gb/s SATA interface or a 6-Gb/s SAS 2.0 interface for superior data protection at industry-leading speeds, along with optional power saving modes with PowerChoice™.

Features and Benefits

  • Fourth-generation, enterprise, nearline drive designed for 24×7 operation
  • Up to 2TB capacity for data-hungry enterprise business applications
  • Best-in-class enhanced rotational vibration tolerance ensures unrivalled performance in high-density applications for continuous data access
  • Enhanced efficiencies with PowerChoice™ host-selectable power options for unprecedented savings (up to 35 percent) during slow or idle periods
  • Proven reliability with multi-drive firmware maximized for enterprise system availability
  • Robust performance with dual processor technology and ramp load technology
  • Provides business sustainability with Seagate Unified Storage architecture
  • 6Gb/s SAS performance with error detection and correction (IOEDC/IOECC) capabilities for the ultimate in data integrity
  • Government-grade Self-Encrypting Drive (SED) option for TCG-compliant/AES-128 security cuts IT drive retirement costs while securely protecting data.*
*SED option for SAS models only. Requires TCG-compliant host or controller support.
