Seagate Momentus 7200.4 250GB SATA Drive

The Seagate Momentus 7200.4 ST9250410AS is a 2.5-inch internal hard drive with a 250GB capacity and a 7200 RPM spindle speed. It connects via a SATA 3.0Gb/s interface and includes 16MB of cache. The drive measures 9.5mm in height and is supplied as a bare drive without packaging accessories.

Suitable Uses and Limitations

This drive suits older laptops, small form-factor PCs, workstations and non-mission-critical blade servers that accept a 9.5mm 2.5-inch SATA drive. It is not for systems requiring capacities above 250GB, interfaces faster than SATA 3.0Gb/s, or mission-critical server environments demanding enterprise-grade reliability. Buyers needing solid-state speeds or larger storage should consider other options.

Sustained Load Behaviour

Under sustained workloads the 7200 RPM rotation speed maintains consistent data throughput for sequential read and write operations. Native Command Queuing optimises command order to reduce head movement during concurrent requests. The 16MB cache buffers repeated access patterns, while G-Force Protection parks the heads if excessive vibration is detected during operation.

Questions about this item

Does my laptop need a 2.5-inch SATA bay that accepts a 9.5mm-high drive for this ST9250410AS to fit?

Yes, the drive is a 2.5-inch form factor with a maximum height of 9.5mm and uses a SATA 3.0Gb/s interface, so the host must provide a matching bay and connector.

Will this 7200 RPM drive work in a system that originally shipped with a 5400 RPM SATA drive?

Yes, both drives use the same SATA 3.0Gb/s interface and 2.5-inch form factor, so the 7200 RPM unit can replace the 5400 RPM drive without hardware changes.

How can I confirm the drive is operating at its rated 7200 RPM and 16MB cache after installation?

Use a system information tool or SMART utility to verify the reported rotation speed of 7200 RPM and cache size of 16MB, and check that the SATA link negotiates at 3.0Gb/s.
