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.
Compromise nothing
Proven Hitachi reliability comes standard.
