Press Release

The Ultrastar C10K1200 is the industry’s highest-capacity 10,000 RPM, enterprise-class hard drive, delivering a massive 1.2TB of storage space. Providing a capacity extension to HGST’s proven Ultrastar C10K900 product line, the 2.5-inch Ultrastar C10K1200 features a SAS 6Gb/s interface for reliable data throughput, a 64MB cache buffer for optimized read/write response time, and a fast 10K RPM rotational speed for reliable high-performance computing. All this, combined with the drive’s low power, high capacity and high performance attributes, results in higher density servers, blades and network storage arrays that helps reduce space requirements, lowers cooling costs and improves total cost of ownership (TCO).


  • Highest capacity 10,000 RPM drive
  • Field-proven, reliable design Seamless extension to the C10K900 family
  • High-performance 6Gb/s SAS for reliable data throughput
  • Large 64MB cache buffer manages data efficiently
  • Halogen-reduced design and industry-best power utilization for most eco-friendly 10K SFF hard drive
  • Space and/or power constrained environments
  • Enterprise-class servers and networked storage arrays Blade and 1U/2U rack-mounted servers
  • Databases and Online Transaction Processing (OLTP)
  • High performance computing and other 24x7 applications
  • Cloud computing
