Seagate Constellation.2 ST9250610NS 2.5" SATA Enterprise Hard Disk Drives

Bulk data storage in a small footprint.

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

Unparalleled power savings.

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.

Big storage for small spaces.

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.

Secure self-encryption.

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.
