Reliable, high-capacity storage for mobile applications

Travelstar

 5K320 is a 5400 RPM 2.5-inch hard drive with capacities ranging from 80GB to 

320GB. The 160GB per platter one- and two-disk models are designed for use in notebook 
PCs, set-top boxes, gaming consoles and other mobile applications. The 5K320 raises the 
standard for hard drive reliability with design enhancements that include altitude-sensing
Thermal Fly-height Control (TFC), an improved actuator latch and fourth generation 
perpendicular magnetic recording (PMR) head technology. Along with the attention to 
ruggedness, Hitachi continues to deliver excellent performance and low-power leadership. 
Designed to support the multi-tasking needs of consumers and commercial users balancing 
mobile computing and movies, music, photos and games on the go, Travelstar 5K320 
delivers the right capacity and performance options to meet the needs of IT and consumer 
electronics manufacturers. Hitachi offers optional hard-drive-level encryption for users looking 
for increased data security and models with enhanced availability to deliver high-capacity 
storage for non-stop environments. 

Data security option

Travelstar 5K320 features optional Bulk Data Encryption (BDE) with a SATA 1.5Gb/s interface 
for hard-drive-level data security. The data is scrambled using a key as it is written to the disk 
then descrambled with the key as it’s retrieved, giving users a higher level of data protection 
than traditional password-based security previously available. Another bene

fi

 t is that it speeds 

and simpli

fi

 es the drive re-deployment process. By deleting the encryption key, the data on the 

drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.

Enhanced Availability (EA)—for 24x7 access to data

Hitachi provides enhanced-availability models that employ speci

fi

 c microcode to allow the 

Travelstar 5K320 to deliver 24x7 access to data. These models broaden the product line 
to make it more suitable for data-intensive applications requiring round-the-clock operation. 
The 5K320 provides high capacity, performance, durability and ef

fi

 cient power utilization 

on a proven platform for quality and reliability. EA models support the stringent demands 
of “always-on” applications in lower-transaction environments.
