Size:500 GB 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. This family of high-capacity enterprise-class hard drives is 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 8W), 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 and high-capacity 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 (3Gb/s or 6Gb/s) 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. Additionally, the Constellation ES drive carries a 5-year limited warranty.
