HGST Hard Drive 0B36404 8TB ULTRASTAR ES 3.5 inch SATA 256MB 7200RPM 512E SE HC320 Bare

As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on lower 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, Ultrastar DC HC320 is an 8TB HDD that helps address economic and access requirements of many traditional IT workloads. Lower capacity drives also help address architecture limitations. The Ultrastar DC HC320 is designed for traditional storage and server applications as well as distributed and scalable computing, including block and file storage architectures, providing fast 7200 RPM performance and lower acquisition cost to help ease budget constraints.
