Advanced Power and Security Engineering

The Ultrastar DC HC555 combines HelioSeal technology with energy-assisted perpendicular magnetic recording (ePMR) to lower total cost of ownership across data centers. For security-sensitive environments, available Self-Encrypting Drive (SED) options provide hardware-level encryption and instant cryptographic erase capabilities. With an idle power draw of just 5.3W on SATA models, it lowers energy requirements while maximizing storage density. The integrated Triple-Stage Micro Actuator provides precise head positioning over increased tracks-per-inch to maintain fast, stable throughput.
