Data Sheet
™
Constellation
2.5-inch Tier 2/nearline drive
with the lowest enterprise power usage
500 GB and 160 GB • 7200 RPM • SAS 6Gb/s,
SAS 3Gb/s, SATA 3Gb/s and SATA 1.5Gb/s
Key Advantages
•
Industry’s first 2.5-inch, 15-mm enterprise-class nearline drive for dense,
space-constrained data centers
•
Lowest operating power and enhanced PowerChoice™ host-selectable
power options for unprecedented power savings (up to 54 percent—as low
as 1.1 W) during slow or idle periods
•
The industry’s highest-reliability 7200-RPM drive, designed for 24x7
operation
•
Best-in-class rotational vibration tolerance ensures unrivalled performance
in high spindle-density applications, and multi-drive firmware maximizes
system availability.

Constellation™
2.5-inch Tier 2/nearline drive
with the lowest enterprise power usage
Built On Seagate Unified Storage architecture
•
Small form factor—15 mm z-height provides a dense,
eco-friendly, robust platform for easy integration.
•
SAS 2.0—6 Gb/s enables larger topologies at higher
throughput and provides a higher signal strength over
longer distances for improved scalability.
•
Self-Encrypting Drive option for government-grade
security.
Enhanced Choices With Enterprise Capabilities
•
PowerChoice host-selectable power options (1
through 4) further reduce power consumption to an
unprecedented low of 1.1 W.
•
With a choice of either SATA 3Gb/s or SAS 6Gb/s
interfaces, utilizes perpendicular recording technology
to deliver the industry’s highest-capacity 2.5-inch
nearline drive
•
Enterprise-class firmware features and best-in-class
rotational vibration tolerance maximizes system
availability and performance in multi-drive systems.
Seagate proprietary Workload Management technology
helps systems keep drives cool.
•
The best 7200-RPM reliability for 24x7 business-critical
applications with an MTBF of 1.2M hours and an
nonrecoverable error rate of 1 sector per 10E15—from a
trusted source and backed by a 5-year limited warranty.
