The Constellation 7200 hard drive enables 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 SATA drives deliver cost-effective, eco-friendly nearline storage.

• 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*
