ES drive for enterprise 7200-RPM environments enables cost-effective, highly
efficient storage with the highest capacities, best-in-class reliability,
leading 6Gb/s SAS performance, optimized power and cooling, and optional
government-grade security, all backed by Seagate enterprise service and
support. The 2TB capacity can store an unprecedented 76TB per square foot,
maximizing floor space at the lowest $/GB. With the lowest power consumption
and highest temperature tolerance for a 3.5 inch enterprise drive, the
Constellation ES drive optimizes chassis performance in tiered storage
solutions. It is the only drive offering a choice of traditional SATA 3Gb/s
interface for seamless integration, or the industry-leading 6Gb/s SAS
interface for a more reliable, scalable and sustainable high-performance
enterprise solution. Seagate Constellation℠ES What the experts are saying...

Between Failures Self-Encrypting SAS models require TCG-compliant host or
controller support “What if I told you that you could have Velociraptor level
performance (and more) with almost seven times the capacity? Seagate's
Constellation Hard Drive fits that bill to a T. It Outperforms the
Velociraptor by almost 20mb/s on maximum read performance, and with 2TB of
space it puts the 300GB capacity of the Velociraptor to shame.†- Lanoc
Reviews, January 2010 “I personally think that Seagate is on the right track
with Constellation ES series and i am sure this is not the end of the
Enterprise line for Seagate. Great fast drives and great performance. 9/10!†-
Umlan, January 2010 "Rorke Data's HD video and 3D film post production
customers need both the increased capacity and the 6Gb/s SAS performance of
the Constellation℠ES drives to meet their growing needs, especially in the
world of 3D. Our Galaxy Aurora RAID systems take full advantage of the high-
capacity Constellation℠ES drive by packing 72TB in under 9 inches of rack
space while delivering sustained transfer rates of 3300MB/s," - Joe Rorke,
vice president of marketing, Rorke Data Seagate Enterprise Family Hard Drives
