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 24×7 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.
