From the Manufacturer

The Seagate® Constellation.2™ drive is the only 2.5-inch enterprise-class hard drive delivering both 1TB capacities and enterprise reliability at the industry’s lowest power consumption for storage-hungry nearline applications. Self-Encrypting Drive (SED) and FIPS 140-2 Validated™ SED security options available to help you protect your data.

• Maximizes data center footprint with up to 76TB per square foot
• Energy efficient storage at under 3.9 watts (idle)
• Highest nearline reliability with an MTBF of 1.4M hours
• 6Gb/s performance in both SAS and SATA interfaces

Constellation.2 hard drives reduce per-gigabyte cooling and energy costs by packing high capacities into an SFF, low-power-consumption drive.

Included Seagate® PowerChoice™ technology can further reduce energy costs by empowering IT organizations to tailor systems for optimal performance and power consumption.

Constellation.2 hard drives can help you deploy additional enterprise storage without expanding your data center.

With its 15mm z-height, the 1TB model is the first 2.5-inch hard drive capacity-optimized for dense, space-constrained data centers. This model can help you store twice as much data in the same footprint, supporting up to 76TB of storage per square foot.

Constellation.2 hard drives are available as Self-Encrypting Drive models. SED options can improve data-at-rest security and reduce drive retirement costs.

Meets regulatory data security compliance requirements and is FIPS 140-2 Validated™ to protect Sensitive but Unclassified and Protected class data.

Constellation.2™ 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 PowerChoice™ 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 drive’s settings for optimal performance and energy usage. The result: power savings of up to 54% over traditional 3.5–inch drives.

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

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

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

Moreover, Seagate Instant SecureErase™ 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.
