Western Digital Ultrastar DC HC555 14TB Enterprise Data Center Hard Drive, SATA Self-Encrypting Drive (SED), 7200 RPM | WD 0B48716

The Western Digital Ultrastar DC HC555 14TB enterprise hard drive delivers high-capacity storage engineered for high-intensity, 24x7 multi-user data center environments. Utilizing field-proven Conventional Magnetic Recording (CMR) technology on a 3.5-inch platform, this drive seamlessly integrates into cloud architectures, hyperscale deployments, and big data infrastructures. Designed with energy-assisted perpendicular magnetic recording (ePMR) and HelioSeal technology, the HC555 provides dependable performance while keeping operational expenditures low. 14TB capacity in a 3.5-inch enterprise form factor Interface: SATA 6Gb/s Conventional Magnetic Recording (CMR) technology Self-Encrypting Drive (SED) support with TCG-Enterprise and Sanitize Crypto Scramble/Erase options 7200 RPM spin speed with 4.16 ms average latency 512MB data buffer for smooth high-speed access Sustained transfer rate up to 269 MB/s (257 MiB/s) HelioSeal helium-filled design for reduced power profiles Rotational Vibration Safeguard (RVS) dual-sensor protection Triple-Stage Micro Actuator for accurate track positioning 2.5M-hour MTBF with 0.35% Annualized Failure Rate (AFR) 5-year limited warranty backed by Western Digital support 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. Data Sheet
