320GB 7200 RPM laptop drive

The HGST Travelstar Z7K500 is a 2.5-inch internal hard drive built for notebook PCs, external enclosures and gaming consoles. Its 7mm height fits slim chassis where a standard 9.5mm drive will not install. The SATA 6.0Gb/s interface connects directly to any compatible mobile or desktop controller.

320GB capacity with 32MB cache

At 320GB the drive holds an operating system, applications and a moderate media library; heavier workloads such as large game collections or video projects will exceed the available space. Advanced Format 4096-byte sectors with 512-byte emulation improve error correction and areal density on the single platter. The 7200 RPM spindle and 32MB cache deliver the highest PCMark Vantage scores in this class.

7mm SATA drop-in for thin laptops

The bare drive measures 100mm by 70mm and requires only a standard SATA data and power connection — no extra cables, brackets or drivers. Low power consumption and halogen-free construction reduce thermal load in compact enclosures. Self-encrypting variants are available separately for users who need hardware-based data protection.

Questions about this item

Will the 7mm height Travelstar Z7K500 fit in the 9.5mm bay of my older laptop?

The drive measures 7mm tall, 70mm wide and 100mm long. It is designed as a direct replacement for standard 9.5mm HDDs, so it fits the larger bay without an adapter.

How can I verify the SATA 6.0Gb/s link is active after installation?

Check the negotiated speed in your BIOS or UEFI storage information; it should report 6.0Gb/s. In Windows, open Device Manager, view the drive properties under the Details tab and confirm the current link speed shows 6Gbps.

Does the bare drive package include mounting screws or a SATA cable?

The 0J26003 ships as a bare drive only. You must supply any 2.5-inch mounting screws, brackets or SATA data and power cables required by your laptop or enclosure.
