Advanced write caching enables maximum sustained transfer speeds of 285 MB/s. Seagate Secure provides AES-256 hardware-based encryption and password protection for data-at-rest security.

Power Management Features

PowerChoice and PowerBalance technologies allow customization of power consumption during active and idle states. Typical operating power consumption is rated at 9.4 watts.
