Model Number: 0B47741 Ultrastar HC555 Data Center HDD Storage – 12TB

Western Digital Ultrastar DC HC550 12TB Enterprise HDD (0B47741) – High-Capacity Data Center Storage

Body Content: The Western Digital Ultrastar DC HC550 12TB (Model: 0B47741) is engineered to meet the rigorous demands of modern data centers and cloud service providers. As part of the world-renowned Ultrastar line, this 3.5-inch enterprise hard drive delivers an unbeatable combination of capacity, performance, and power efficiency. Designed for 24/7/365 operation, the 0B47741 provides the rock-solid reliability required for mission-critical Big Data applications and high-density storage arrays.

HelioSeal® Technology for Peak Efficiency At the heart of the Ultrastar HC550 is Western Digital’s proprietary HelioSeal technology. By sealing the drive with helium—which is one-seventh the density of air—internal turbulence is reduced. This allows for thinner platters and a more stable recording environment. For you, this means lower power consumption, cooler operating temperatures, and a significantly higher 2.5 million hour MTBF (Mean Time Between Failures) rating.

Optimized for Enterprise Workloads The 0B47741 is built to handle heavy workloads of up to 550TB per year. Whether you are deploying an enterprise-grade NAS (Network Attached Storage), a private cloud, or a massive RAID backup system, this drive’s 7200 RPM performance and large cache ensure rapid data throughput and minimal latency.

Advanced Security & Data Integrity Protecting your data is paramount. The Ultrastar 12TB HDD includes advanced error-correction technologies and is available with Self-Encrypting Drive (SED) options. This ensures that your sensitive corporate data remains secure from the moment it is written to the platter until the drive is decommissioned.
