As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on mid-range capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC300 series is a proven air-filled design that delivers up to the industry leading 10TBof capacity to help address the economic and access-density requirements of many data center workloads. Ideal for storage and server applications, as well as distributed and scalable computing (including block and file storage architectures), the Ultrastar DC HC300 series provides fast 7,200 RPM spindle speeds and is offered in either 6Gb/s SATA or 12Gb/s SAS interface with advanced format 512e sector size.
Designed for data centers and demanding environments, Western Digital Ultrastar drives have a MTBF rating of at least two million hours and are built for yearly (24x7x365) operation.

Western Digital Ultrastar drives are built with Enhanced Rotational Safeguard (RVS) technology, which monitors and corrects linear and rotational vibrations in real-time for improved performance.
Dynamic Fly-Height technology utilizes real-time read/write head adjustments for consistent performance, reduced errors, and optimized reliability. Dual-Stage Actuator technology improves positional accuracy over the data track. The primary actuator provides course displacement using conventional methods, whereas the secondary actuator uses piezoelectric motion to fine-tune the head positioning to a higher degree of accuracy.
Western Digital Ultrastar hard drives are extensively tested with a variety of storage systems, SATA controllers, and host bus adapters to ensure they are a simple plug-and-play storage solution.
