Leadership performance

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.

Best-in-class power performance

Power management innovations designed into the Ultrastar C10K900 enable industry-leading power efficiency, up to 28% better than competing drives, and translate into reduced power requirements and lower cooling costs. Hitachi Advanced Power Management technology, with multi-state idle modes, maintains compatibility with the INCITS T10 Technical Committee standards direction and can be pre-programmed or manually initiated in the system. Ultrastar C10K900 continues the Hitachi tradition of environmental leadership with its halogen-reduced components and focus on low power consumption, and carries the Hitachi EcoTrac classification.

Driving the small form factor transition

Ultrastar C10K900 delivers capacity parity with 3.5-inch 10K drives, providing a massive 900GB of storage space and enabling lower total cost of ownership for many Enterprise environments, especially networked storage arrays. When faced with space and power limitations, the Ultrastar C10K900 is an efficient solution for online transaction processing, intensive data analysis and multi-user applications. Some models of the C10K900 also offer Bulk Data Encryption for hard-drive-level data security. These self-encrypting models are designed to the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification and allow customers to reduce costs associated with drive retirement and extend drive life by enabling swift and secure repurposing of drives.
