Superior performance in a small package
The Ultrastar
 C10K147 is Hitachi’s first small form factor (SFF) 2.5-inch enterprise hard drive. 
Leveraging the company’s proven enterprise-class technology, the Ultrastar C10K147 delivers 
performance and reliability with lower power consumption and space requirements to meet 
the needs of real-time server environments. With features like Thermal Fly-height Control 
(TFC) and end-to-end data protection, the Ultrastar C10K147 provides enhanced error detec-
tion for superior data integrity. In addition, Rotational Vibration Safeguard (RVS) maintains 
system robustness in multi-drive system environments. 
 
Configuration flexibility
The Ultrastar C10K147 provides an industry-standard Serial Attached SCSI (SAS) interface 
offering customers improved performance and configuration flexibility while requiring less 
power. Hitachi’s dual-port configuration supports multiple data paths for optimum reliability 
and performance for online transaction processing and other compute-intensive applications.
