Travelstar 5K320 250GB SATA 1.5Gb/s BDE
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 benefi t is that it speeds and simplifi 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.
