Features




Saves energy and money.


Constellation.2Â? hard drives deliver the lowest power consumption in the industry.These hard drives also operate at just 3.9W when idle;which can be further reduced to an astounding 1.1W with enhanced PowerChoiceÂ? technology options.


Purpose-built for enterprise environments, PowerChoice is based on the T10-compliant power management standard.This technology enables you to tailor the Constellation.2 hard driveÂ?s settings for optimal performance and energy usage. The result: power savings of up to 54% over traditional 3.5Â?inch drives.


Simply put,Constellation.2 hard drives deliver the lowest power usage ever offered in an enterprise-class nearline driveÂ?without any performance degradation.








Builds better solutions.


System integrators and IT professionals can leverage Constellation.2 hard drive features like these to build optimal data storage solutions:



  • Enterprise-class firmware and best-in-class rotational vibration tolerance maximize system availability and performance in multi-drive systems

  • Choose 6Gb/s SAS for improved data integrity, scalability over long distances and fastest data access

  • The SATA 6Gb/s interface is ideal for fast, economical nearline (Tier2) performance





Self-encryption for optimal ROI.


The TCG-compliant, Self-Encrypting Drive1 option keeps data secure where it lives: on the hard drive.


Moreover, Seagate Instant SecureEraseÂ? technology renders all data on the SED unreadable in less than a second. This feature eliminates the need to overwrite or physically destroy drives, allowing organizations to securely return, repurpose or sell their hard drives.
