Travelstar™ Z7K320

High-performance, quiet HDD solution for mobile applications
Travelstar™ Z7K320 is the industry's first 7200 RPM, 7mm, 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 HDD s, for use in notebook PCs, external storage and compact systems. The Z7K320 offers design flexibility to accommodate new thinner and more robust devices/systems and delivers up to 18% better application performance than 5400 RPM models of the same capacity. Along with continued focus on superior shock protection and low-power consumption, Hitachi delivers best-of-breed acoustics. Hitachi offers optional hard-drive-level encryption for increased data security and models with enhanced availability to deliver high-performance storage for non-stop environments. Travelstar Z7K320 provides the right balance of performance and capacity to meet the multi-tasking needs of commercial and consumer users on the go.
Data security option
Travelstar Z7K320 is the fourth generation to feature optional Bulk Data Encryption (BDE ) for hard-drive-level data security. Hitachi has designed these self-encrypting drives to the Trusted Computing Group (TCG) Opal Storage Security specification, which is expected to become an industry standard. 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.
Enhanced Availability (EA)—for 24x7 access to data
Hitachi provides enhanced-availability models of the Travelstar Z7K320 that deliver 24x7 access to information for data-intensive applications requiring round-the-clock operation. The new, slimmer profile provides for additional cooling, especially important in dense blade server designs. The Z7K320 provides high capacity, performance and durability on a proven platform for quality and reliability. EA models support the stringent demands of “always-on” applications in lower-transaction environments.
Hitachi quality and service
Hitachi mobile hard drives are designed to the highest quality standards and contain field-proven components. Hitachi provides worldwide technical support and integration services to enable global customers to bring their products to market quickly.
