HGST Travelstar Z5K500 500GB SATA laptop drive

This 2.5-inch internal hard drive delivers 500GB of storage for notebooks, security systems and gaming consoles. Its 7mm z-height design fits thin ultrabooks that cannot accept standard 9.5mm drives. The SATA 6.0Gb/s interface provides broad compatibility with existing laptop bays and external enclosures. It targets users who need affordable capacity with low power draw.

7mm form factor with Advanced Format 512-byte

The second-generation 7mm height allows direct replacement of thicker 9.5mm drives without adapters or spacers. Advanced Format technology uses industry-standard 4K sectors while presenting 512-byte emulation for legacy operating system support. Halogen-free construction meets eco-friendly design requirements. Low power consumption helps extend battery life in mobile devices during daily computing tasks.

5400 RPM with 8MB cache for everyday workloads

The 5400 RPM spindle speed balances quiet operation with sufficient throughput for typical laptop workloads. An 8MB cache buffers frequent read and write requests to smooth performance. Average seek time of 13ms and average latency of 5.5ms reflect standard mechanical drive responsiveness. Self-encrypting variants are available separately for users who require hardware-based data protection.

Questions about this item

Does the SATA 6.0Gb/s interface limit the 500GB drive's transfer speed?

The SATA 6.0Gb/s interface provides a 6Gb/s link. The 5400 RPM rotational speed and 8MB cache determine the actual sustained throughput you will see in daily use.

Will the 7mm height fit a bay designed for a 9.5mm drive?

The drive measures 7mm tall, 70mm wide and 100mm long. It fits 2.5-inch bays that accept 7mm or 9.5mm heights; a spacer may be needed for the deeper 9.5mm slot.

How is the drive installed in a laptop and what step is often missed?

Slide the 2.5-inch SATA drive into the bay, secure it with the caddy or screws, and connect the SATA data and power cables. The step often missed is ensuring the SATA connectors are fully seated on both the drive and the motherboard.
