Data Sheet

Travelstar™ Z7K320

2.5-Inch Mobile 7200 RPM 7mm Hard Disk Drives

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 HDDs, 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, HGST delivers best-of-breed acoustics. HGST 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. 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 self- encrypting drives designed to the Trusted Computing Group (TCG) Opal Storage Security specification, please contact your HGST representative.

		Enhanced Availability (EA)—for 24x7 Access to Data
		HGST 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.

320GB, 250GB and 160GB 7200 RPM SATA 3Gb/s

HTS723225A7A364, HTS723216A7A364, HTS723216A7A361, HTE723225A7A364, HTE723232A7A364 specifications

The Hitachi HTS723225A7A361, HTS723216A7A365, HTE723232A7A364, HTS723225A7A364, and HTS723216A7A361 are part of the Hitachi Travelstar line of hard disk drives (HDDs), known for their reliability and performance in various computing environments. These drives are designed largely for mobile and desktop applications, making them suitable for laptops, external storage solutions, and all-in-one PCs.

A standout feature of these drives is their capacity, with the HTS723225A7A361 and HTS723225A7A364 offering a substantial 250 GB of storage, while the HTS723216A7A365 and HTS723216A7A361 provide 160 GB. This amount of storage makes them ideal for users who need to store large amounts of data, including multimedia files, applications, and system backups.

In terms of performance, these drives have a spindle speed of 5400 RPM, which balances speed and efficiency. While 7200 RPM drives may offer faster data access times, the 5400 RPM models are often preferred in mobile applications due to their reduced power consumption and heat generation. This energy-efficient design not only extends battery life in portable devices but also contributes to a quieter operation.

One of the key protective features incorporated in these Hitachi models is the Shock Sensor technology. This innovative feature detects sudden shocks or impacts and temporarily locks the drive's read/write heads, preventing potential data loss or physical damage. Additionally, the drives employ Advanced Format technology, which enhances data integrity and increases storage capacity by effectively utilizing sectors.

The Hitachi HDDs also implement a S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) system that continually monitors the drive’s health status and alerts users to potential issues before they lead to failure. This proactive approach is vital for maintaining data security, especially in environments where data integrity is crucial.

Moreover, these drives are designed with a focus on broad compatibility, making them suitable for a range of operating systems and devices, from laptops to gaming consoles. Their durability, combined with a design that minimizes power consumption, makes the Hitachi HTS723 series a favored choice among both consumers and professionals.

In conclusion, the Hitachi HTS723225A7A361, HTS723216A7A365, HTE723232A7A364, HTS723225A7A364, and HTS723216A7A361 hard drives are excellent choices for users prioritizing performance, capacity, and reliability. With features designed to safeguard data integrity, these drives continue to play a significant role in data storage solutions.
