Ultrastar DC HC300 Series

  • Medium Capacity for High Access-Density Requirements
  • Solves Access Density Challenges

  • Economical Capacity – 4TB, 6TB, and 8TB models for lower acquisition cost
  • High Performance – Fast data access with 7200 RPM speed, transferring up to 255 MB/s
  • Drop-In Ready – SAS and SATA options support traditional servers and storage



Delivering Economics and Access Speed to Data Center Applications and Workloads

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-platform design that delivers up to 8TB of 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 performance and lower acquisition cost to help ease budget constraints.
