HGST Travelstar 500 GB 2.5" 7200 RPM

The HGST Travelstar Z7K500 is a 500 GB 2.5-inch internal hard drive that spins at 7200 RPM. It connects through a SATA 6Gb/s interface and carries a 32 MB cache. The drive uses Advanced Format with 4,096-byte sectors for improved capacity and error correction. It is built in a 7 mm height to fit modern notebook bays.

Suits laptops and consoles needing a 7 mm 7200 RPM

This drive fits notebook PCs, external enclosures and gaming consoles that accept a 7 mm 2.5-inch SATA drive. Buyers who need a thinner profile than 7 mm, who require solid-state speeds, or who want capacities above 500 GB should consider other options. The 500 GB per platter design targets direct replacement of standard 9.5 mm drives in compatible systems.

SATA 6Gb/s interface with 32 MB cache

The single specification that decides fit is the SATA 6Gb/s interface combined with 32 MB cache. Verify that the host system supports SATA 6Gb/s and has a 2.5-inch bay that accepts a 7 mm drive height. The Advanced Format 4K sector size also requires operating system or controller support for proper alignment.
