The lineup includes 2.5" Constellation HDDs with capacities of 160GB and 500GB, and 3.5" Constellation ES HDDs with capacities of 500GB, 1TB and 2TB. Both series have Seagate's PowerChoice technology, which promises power savings of up to 54 percent.
The Constellation 2.5-inch hard drive is offered in capacities of 160GB and 500GB with both 3 Gbps SATA and new SAS 2.0 interface running at 6Gb/s speeds. As the first SAS 2.0 nearline drive, the Constellation hard drive enables larger external storage topologies, 100% faster data throughput and higher signal strength over greater distances – dramatically increasing storage scalability. The Constellation family will begin shipping this quarter.
The 3.5-inch Constellation ES hard drive will be available in 500GB, 1TB and 2TB capacities, and with an enterprise-class SAS interface as well as a SATA version, and provides best-in-class capacity and performance. As the world’s only 7200-rpm 3.5-inch hard drive providing up to 2TB of storage, the record-setting capacity of Constellation ES hard drives are ideal for 3.5-inch based external storage architectures. With Constellation ES hard drives, customers don’t have to sacrifice performance in order to gain the highest capacities. The Constellation ES hard drive will ship in calendar Q3.
With Seagate’s innovative PowerChoice technology, both Constellation hard drive models deliver the highest power-reduction savings ever offered in an enterprise-class HDD, and provide flexible, user-manageable options to deliver power savings without sacrificing performance, data integrity, or reliability. In addition, the Constellation family of drives are backed with field-proven, enterprise-grade reliability and rated at a full 1.2 million hours MTBF.
Delivering on Seagate’s commitment to add security features throughout its product portfolio, the Constellation family of drives are offered with optional self-encrypting drive (SED) technology and provide government-grade data security through the drive’s life cycle. SED technology makes drive retirement and disposal easy by eliminating the need for the numerous manual processes involved which are often incomplete, complex, expensive, or prone to error. For critical information that must remain secure, and because all systems are eventually retired, whether being relocated, re-purposed, or disposed of, the information on a Constellation SED hard drive remains AES-safe.
