Seagate® Constellation.2™ SATA 6Gb/s 250GB Hard Drive
The Constellation 7200 hard drive enables secure, manageable nearline storage solutions in 2.5" chassis — either direct attach or in a tiered storage environment — at the lowest power usage without compromising performance or reliability. Constellation 500GB SAS drives with self-encrypting drive technology deliver cost-effective, secure enterprise-class storage for nearline applications.
Key Features and Benefits
Industry’s first 2.5-inch 1TB capacity-optimized drive for dense, space-constrained data centers allows you to store twice as much data in the same footprint.
Build highly efficient bulk storage solutions while lowering your power consumption costs
Designed for robust 24x7 operation with a 1.4M hour mean-time-between-failure (MTBF) rating
Best-in-class rotational vibration tolerance ensures unrivaled performance in high spindle-density applications, and multi-drive firmware maximizes system availability
Choose from 6Gb/s SAS with improved data integrity, scalability and fastest data access or SATA 6Gb/s for economical 7200-RPM performance
TCG- compliant, Self-Encrypting Drive (SED) security option cuts IT drive retirement expenses while securely protecting data*
