What this drive is and who it fits
The HGST Travelstar 7K500 HTE725032A9A364 is a 320 GB 2.5-inch laptop hard drive that spins at 7200 RPM with a 16 MB cache. It uses a SATA interface and a plug-in module form factor. The unit is supplied new and suits owners of compatible notebooks who need a direct replacement or a capacity upgrade within the 2.5-inch SATA bay.
The specification that decides compatibility
The drive connects through a SATA/300 interface and measures 2.5 inches wide with a 0.4-inch height. Verify that the target laptop accepts a 2.5-inch SATA drive of this thickness before purchase, as some ultra-thin chassis require a slimmer 7 mm or 5 mm module. The 320 GB capacity is fixed and cannot be altered.
Behaviour under sustained load
The 7200 RPM spindle speed and 16 MB buffer are designed to maintain steady throughput during extended read or write sessions such as large file transfers or operating system updates. Hitachi's power management and operating shock features aim to keep performance consistent while the drive remains installed in a mobile system.

Questions about this item
How does the 7200 RPM speed affect real-world laptop performance?
The 7200 RPM spindle speed delivers faster data access than 5400 RPM drives, improving application load times and overall system responsiveness in a notebook.
What does the SATA/300 interface standard mean for transfer speeds?
The SATA/300 interface caps the maximum theoretical transfer rate at 300 MB/s, which limits sustained throughput even if the drive's internal speed is higher.
Will the 0.4 inch height fit my laptop's 2.5 inch drive bay?
At 0.4 inch tall, 2.8 inch wide and 3.9 inch deep, this drive matches the standard 2.5 inch form factor used in most laptop drive bays.
