Data Sheet
Travelstar™ Z5K320
2.5-Inch Mobile 5400 RPM
7mm Hard Disk Drives
Quiet, Rugged, Low-Power HDD Solution for Mobile Applications
Travelstar™ Z5K320 is a 7mm,5400 RPM 2.5-inch hard drive with capacities ranging from 160GB to 320GB.The 320GB per platter one-disk models are designed as a direct replacement for standard 9.5mm HDDs,for use in notebook PCs,external storage and gaming consoles. The Z5K320 also accommodates new thinner and more robust device designs.These models deliver best-of-breed acoustics for near silent operation.Along with continued focus on superior shock protection and low power consumption,HGST leads on the environmental front with its Halogen-free production.HGST offers optional hard-drive-level encryption for increased data security and models with enhanced availability to deliver high-capacity storage for non-stop environments.Travelstar Z5K320 delivers the right balance of capacity, power-management and design flexibility to meet the needs of mobile applications in an eco-friendly footprint.
Data Security Option
Travelstar Z5K320 is the fourth generation to feature optional Bulk Data Encryption (BDE) for hard-drive-level data security.With BDE,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 the highest level of data protection available.It also 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.For information about the selfencrypting drives designed to the Trusted Computing Group (TCG) Opal Storage Security specification,please contact your HGST representative.
