Product identity

This is a Seagate Momentus 5400.4 laptop internal hard drive with 160GB capacity and a 2.5 inch form factor. It connects via a SATA 3.0Gb/s interface and spins at 5400 RPM with an 8MB cache. The drive is supplied as a bare unit in new condition.

Who it suits

The drive fits older notebooks or external enclosures that accept a 2.5 inch SATA mechanical drive. It is not suited for systems that require a solid-state drive or a larger storage capacity than 160GB. Buyers needing faster access times should consider alternative technologies.

Deciding specification

The SATA 3.0Gb/s interface determines whether this drive will work in a given machine. Verify that the host system provides a compatible SATA port and can accommodate a 2.5 inch drive before purchase.

Questions about this item

How can I verify the ST9160827AS is working correctly after installation?

The drive should be detected in BIOS at 160GB capacity with a SATA 3.0Gb/s link. Run a SMART self-test and listen for quiet 5400 RPM operation without clicking.

What is included with the bare drive and what must I source separately?

Only the 2.5" ST9160827AS unit is supplied. You need a SATA data cable, a SATA power connection from the laptop, and mounting screws or a caddy for the 2.5" bay.

Which Momentus 5400.4 capacity should I choose for a standard laptop upgrade?

This listing is the 160GB model (ST9160827AS). Select it if 160GB matches your storage need; other capacities carry different model numbers.
