Travelstar 5K320 is a 5400 RPM 2.5-inch hard drive with large capacities. The 160 GB 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.

Travelstar 5K320 features optional Bulk Data Encryption (BDE) with a SATA 1.5 Gb/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 is retrieved, giving users a higher level of data protection than traditional password-based security previously available. Another benefit is that it speeds and simplifies 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.

Hitachi provides enhanced-availability models that employ specific microcode to allow the Travelstar 5K320 to deliver 24 x 7 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 efficient power utilization on a proven platform for quality and reliability. EA models support the stringent demands of "always-on" applications in lower-transaction environments.
