Key Advantages

• Industry’s first 2.5-inch, 15-mm enterprise-class nearline drive for dense, space-constrained data centers
• Lowest operating power and enhanced PowerChoice™ host-selectable power options for unprecedented power savings (up to 54 percent—as low as 1.1 W) during slow or idle periods
• The industry’s highest-reliability 7200-RPM drive, designed for 24x7 operation
• Best-in-class rotational vibration tolerance ensures unrivalled performance in high spindle-density applications, and multi-drive firmware maximizes system availability.
• Choose SAS for the seamless Tier 2 enterprise experience, with improved data integrity. SAS 2.0 enables faster data access (6Gb/s) and larger topologies over greater distances, increasing system scalability, data throughput and connectivity.
• Government-grade Self-Encrypting Drive security available on SAS models.

Best-Fit Applications

• Storage-hungry business applications
• Storage area networks (SAN) and network attached storage (NAS)
• Maximum-capacity servers and blade servers
• Rich media content storage—audio, video, image
• Reference and compliance data storage
• Enterprise backup and restore—D2D, virtual tape
• Collaboration—email, messaging
• Infrastructure—Web, print, file

Compatibility

This drive is compatible with any of our SAS drive trays and any of our SAS controllers.
