Overview

Constellation ES drives offer the world’s highest capacity at 2TB while providing enterprise robustness for Tier 2/nearline environments. They are differentiated from 3.5-inch desktop drives by offering enterprise-class reliability and superior data integrity with a UER of 1E10-15. Enterprise-class rotational vibration tolerance provides robust protection from chassis and fan vibrations (RV 12.5 rad/sec 20 to 1500Hz). The drives are offered with either a 3-Gb/s SATA interface or a 6-Gb/s SAS 2.0 interface for superior data protection at industry-leading speeds, along with optional power saving modes with PowerChoice™.
