Industry-leading power and performance for the Enterprise

Ultrastar® C10K900 is a 2.5-inch 10,000 RPM hard drive that leads the industry with 18% faster sequential and up to 17% random performance than the nearest competitor. The high performance SAS 6Gb/s interface delivers data reliability, availability and scalability and is the only small form factor SAS drive in the industry to pack a 64MB cache buffer for optimized read/write response time.


  • Built on field-proven, reliable design
  • Industry-best performance in a 10K RPM 2.5-inch form factor
  • 18% faster sequential and up to 17% better random performance than competition
  • Uses 28% less power during operation than competition
  • 900GB capacity continues to support the 3.5- to 2.5-inch form factor transition
  • 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
  • Applications/Environments
  • 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

Capacity (GB) - One GB is equal to one billion bytes when referring to hard drive capacity. Accessible capacity will vary depending on the operating environment and formatting.

Data Buffer (MB) - Portion of buffer capacity used for drive firmware

Seek Time - Excludes command overhead

MTBF (M hours) - MTBF target is based on a sample population and is estimated by statistical measurements and acceleration algorithms under median operating conditions. MTBF ratings are not intended to predict an individual drive’s reliability. MTBF does not constitute a warranty.

MB is equal to Million Bytes
