Leadership performance Ultrastar C10K600 is a 2.5-inch 10,000 RPM hard drive that leads the industry with 18% faster sequential and up to 15% 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 to optimize the read/write response time.Best-in-class power performance Power management innovations designed into the Ultrastar C10K600 enable industry-leading power efficiency and translate into reduced power requirements and lower cooling costs. Hitachi Advanced Power Management technology, with multi-state idle modes, maintains compatibility with T10 direction and can be pre-programmed or manually initiated in the system. Compared to 3.5-inch 10K drives, the C10K600 consumes 70% less space and it is small in design which enables reduced power consumption of up to 65%. Ultrastar C10K600 continues the Hitachi tradition of environmental leadership with its halogen-reduced components and focus on low power consumption, and carries the Hitachi EcoTrac classification.
