The Seagate
Constellation ES drive is the fifth-generation 3.5-inch
hard drive for capacity-optimized 7200-RPM enterprise environments.
It enables cost-effective, highly efficient enterprise storage solutions
with high capacities, best-in-class reliability, leading 6Gb/s performance,
optimized power and cooling, and government-grade data security—all
backed by world-class Seagate enterprise service and support.
The Constellation ES drives are a family of high-capacity enterprise-class
hard drives capable of storing an unprecedented 76TB per square foot
(in its 2TB capacity), maximizing data center floor space at a low $/GB.
Be completely assured knowing this nearline drive optimizes your
3.5-inch chassis performance with the lowest power draw (less than 7.3W),
running cooler in higher-temperature environments. This is perfect for
enterprise-tiered storage solutions or small-to-medium businesses,
which lack the luxury of a temperature-controlled data center.
Employed 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 6Gb/s SAS interface—
with its proven scalability, performance and enterprise features—and the
traditional SATA interface for seamless enterprise integration. With large
capacity drives comes longer RAID rebuild times, but with the new Seagate
RAID Rebuild™ development platform, customers can significantly shorten
rebuild times and minimize productivity losses while protecting critical data.
The Constellation ES drive extends the industry's best field-proven
reliability into a high-capacity nearline drive based on world-renowned
Seagate enterprise experience, including support, design, lifecycle
management and eco-system compatibility. This capacity-optimized
drive offers an MTBF of 1.2 million hours for economical, enterprise-grade
reliability. The Constellation ES implementation of 6Gb/s SAS improves
scalability, which makes 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
and SATA interfaces.
