High-performance 2.5-inch laptop drive

The HGST Travelstar 7K750-500 is a 500GB internal hard drive spinning at 7200 RPM with a 16MB cache. It uses a SATA 3.0Gb/s interface and fits the standard 2.5-inch, 9.5mm form factor. The bare drive is suited for notebook PCs, external enclosures and gaming consoles that need faster mechanical storage.

Build integration and clearance

A 9.5mm height lets the drive slide into most 2.5-inch bays without spacer kits. The SATA 3.0Gb/s connector works with any laptop or caddy that provides a standard SATA data and power header. Advanced Format 512-byte emulation means the drive appears as a conventional 512-byte sector device to the host, so no special driver or BIOS support is required.

Capacity headroom and limits

The single-platter 500GB design delivers the highest 7200 RPM performance in its class while keeping power draw low. It handles operating-system drives, game libraries and media collections that fit within 500GB. Users who need more than 500GB of internal space or who want solid-state latency should look elsewhere.

Questions about this item

How long can the 7200 RPM spindle sustain its speed before thermal throttling?

The 7K750-500 is classified for 24x7 operation, so the 7200 RPM spindle is designed to run continuously without thermal throttling under normal notebook cooling.

What noise and heat levels should I expect from the 9.5 mm drive during all-day use?

The single-platter 9.5 mm design and EcoTrac low-power rating keep acoustic output and heat low enough for thin notebooks and external enclosures running continuously.

Does my laptop need a specific SATA revision or caddy to use this 2.5" drive?

Any notebook with a standard 2.5-inch SATA 3.0 Gb/s bay and a 9.5 mm height clearance will accept the drive without extra adapters.
