The Hitachi Travelstar 5K320 (part no. HTS543280L9A300) is a 2.5-inch mobile hard disk drive with 80GB capacity, designed for laptop and portable storage applications. It features a 5400 RPM spindle speed, 8MB cache buffer, and SATA 3GB/s interface for compatibility with standard mobile drive bays and external enclosures. Typical throughput reaches 60–80 MB/s depending on data location; the lower spindle speed prioritizes power efficiency and heat output over performance. This drive is suitable for secondary storage, archival use, external backup enclosures, and legacy laptop upgrades where capacity and reliability matter more than speed.
