Seagate Constellation ES.2 Hard Drives

The Seagate Constellation ES.2 drive is the fifth-generation 3.5 inch hard drive for capacity-optimised 7,200 RPM enterprise environments. It enables cost-effective, highly efficient enterprise storage solutions with high capacities, best-in-class reliability, leading 6Gb/s performance, optimised power and cooling, and government-grade data security — all backed by world-class Seagate enterprise service and support.

The Constellation ES.2 drives are a family of high-capacity enterprise-class hard drives capable of storing an unprecedented 76TB per square foot (in the 2TB capacity), maximising data centre floor space at a low £/GB. You can rest completely assured, knowing that this nearline drive optimises your 3.5 inch chassis performance with the lowest power draw (less than 10.68W), running cooler in higher-temperature environments. This is perfect for enterprise tiered-storage solutions or for small-to medium-sized businesses, which lack the luxury of a temperature controlled data centre. Additionally, Constellation ES.2 Improved power and cooling efficiencies with low power consumption and enhanced PowerChoice technology. Purpose built for enterprise environments, the PowerChoice feature enables the T10-compliant power management standard, allowing organizations to tailor systems for optimal energy usage resulting in up to 90 percent more power savings.

Used by industry leading enterprise OEMs, system builders and integrators who build cost-effective, high-capacity and eco-friendly enterprise class server and storage solutions, the Constellation ES drive is the first drive that offers both the industry leading SAS interface — with its proven scalability, performance and enterprise features — and the traditional SATA (6Gb/s) interface for seamless enterprise integration. With large capacity drives come longer RAID rebuild times, but with the new Seagate RAID Rebuild development platform, customers can shorten rebuild times significantly and minimise productivity losses while protecting critical data.

The Constellation ES.2 drive extends the industry’s best field proven reliability to a high-capacity nearline drive based on world renowned Seagate enterprise experience, including support, design, lifecycle management and eco-system compatibility. This capacity optimised drive offers an MTBF of 1.2 million hours for economical, enterprise grade reliability. The Constellation ES implementation of 6Gb/s SAS improves scalability, making this drive ideally suited for use in high-end, high-capacity network storage solutions. It is the industry’s first 3.5 inch nearline drive to implement the new SAS 2.0 feature set and is the world’s first 3.5 inch nearline drive to operate at 6Gb/s transfer rates in both SAS.

The Constellation ES.2 drive’s improved data security comes from enterprise proven, industry standard Self Encrypting Drive (SED) technology based on the AES-256 standard and with FIPS 140-21 solutions that protect data where it lives — on the drive. The SED functionality eliminates the need to overwrite or physically destroy drives, enables secure return of drives for warranty or expired lease purposes, and allows organisations to repurpose or sell drives securely.

   Key Advantages

  • Highest capacity enterprise drive for demanding data growth.
  • Fifth-generation SAS and SATA drives designed for 24×7 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 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 Drive (SED) option (AES-256) cuts IT drive retirement costs while securely protecting data where it lives—on the drive.
  • FIPS 140-2 Validated drives protect Sensitive but Unclassified and Protected class data.

   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
