HGST Travelstar Z7K500 500GB 7200RPM 2.5" Drive

The HGST Travelstar Z7K500 is a 500GB 2.5-inch laptop internal hard drive spinning at 7200 RPM with a 32MB cache. It uses a SATA 3.0Gb/s interface and fits a 7mm drive bay. The drive is sold new as a bare OEM unit without retail packaging or cables.

500GB Capacity with 7200 RPM Performance

The single-platter 500GB design provides space for operating systems, applications and daily files on notebook PCs, external enclosures or gaming consoles. Advanced Format 4K sectors with 512-byte emulation improve error correction and storage efficiency. The 7200 RPM spindle speed delivers higher PCMark Vantage scores than slower mobile drives, though the SATA 3.0Gb/s link caps maximum throughput below modern 6Gb/s alternatives.

7mm Z-Height with Shock Protection

At 7mm tall the drive replaces standard 9.5mm drives in thinner ultrabooks and small-form-factor systems without adapters. Built-in Shock Protection and Data Protection System features help safeguard data during mobile use. Low power consumption and halogen-free EcoTrac production reduce heat and environmental impact. The bare-drive OEM packaging means mounting screws and brackets must be sourced separately.

Questions about this item

Will the 7mm 2.5" Z7K500 fit the 9.5mm bay in my older laptop?

Yes, the 7mm height is designed as a direct replacement for standard 9.5mm bays in notebook PCs and consoles.

How can I verify the Advanced Format 512e sectors and 32MB cache are active after installation?

Check the drive properties in your OS or BIOS; they will report 512-byte logical sectors with 4K physical sectors and a 32MB cache buffer.

The bare drive arrives without cables or brackets — what extra parts do I need for a SATA laptop bay?

You only need a standard SATA data and power connection from the laptop; no extra bracket is required for the 7mm form factor.
