The Hitachi Travelstar Z7K320 (HTE723232A7A364) is a 2.5-inch SATA hard drive with 320GB capacity, 7200 RPM spindle speed, and 16MB cache. It interfaces via SATA at 3GB/s throughput, typical for enterprise and mobile workstations from the late 2000s. The drive is designed for external enclosures and portable storage applications where compact form factor and moderate performance are required. Common use cases include external backup solutions, archival storage, and secondary storage for laptop docking stations. Spindle speed and cache size support sequential workloads better than random access patterns.
