Cool and clean

The Ultrastar™ C10K300 drive saves you money on your cooling costs. Compared to its 3.5-inch sibling, power consumption is reduced by up to 65%. Advanced Power Management feature with multi-state idle modes maintains compatibility with T10 direction and can be pre-programmed or manually initiated in the system. In keeping with the Hitachi tradition of respecting the environment, the Ultrastar C10K300 drive also boasts halogen reduced components that are earth friendly. These eco-friendly features qualify the C10K300 for the EcoTrac classification.

Great things do come in a small package

The C10K300 drive delivers the performance and reliability demanded in high performance computing and mission-critical environments. The ultra fast SAS interface running at 6Gb/s improves data reliability, availability and scalability. The small footprint consumes 70% less space compared to standard enterprise class drives. This is the only small form factor SAS drive in the industry to pack a 64MB cache buffer to optimize the read/write response time. When faced with space and power limitations, the Ultrastar C10K300 is an efficient solution for high performance computing environments like online transaction processing, intensive data analysis and multi-user applications. Higher capacity and lower power consumption reduces the total cost of ownership of this drive over previous generations.
