Beskrivelse

Seagate® Constellation.2™ SATA 6Gb/s 1TB Hard Drive


ST91000640NS

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.

Seagate® Constellation.2™ drives are the most energy efficient enterprise drives on the market. Designed for enterprise robustness, Constellation.2 is available in capacities up to 1TB and offers reliable storage for high capacity servers and storage arrays in a minimal footprint.

Features

  • 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
