250 GB 2.5" SATA drive for laptops and consoles

The Seagate Momentus 7200.4 ST9250410ASG is a 250 GB internal hard drive that spins at 7200 RPM with a 16 MB buffer. It connects through a 2.5" SATA 3Gb/s interface. The 2.5-inch form factor fits standard laptop bays and the drive trays used in Xbox and PlayStation consoles. The unit is supplied new.

No bundled accessories or software

The package contains only the bare drive. No mounting bracket, adapter cable, cloning utility or diagnostic tool is included. Installers must reuse any screws or caddies from the original device or source them separately.

Suits owners replacing a failed laptop

This capacity works for a direct swap in older laptops, original Xbox or PlayStation systems where a 2.5" SATA drive is specified. Builders needing more storage, a faster solid-state device or a 3.5-inch desktop form factor should look at something else.

Questions about this item

Does the 7200 RPM spindle require any periodic lubrication or bearing service?

The drive is a sealed unit with no user-serviceable parts, so no lubrication or bearing maintenance is needed during its life.

Will the 3 Gb/s SATA link or the 16 MB cache become the bottleneck during long sequential transfers?

Sustained throughput is limited by the 3 Gb/s SATA interface, which caps real-world speeds well below the mechanical maximum.

How much heat and noise does the 7200 RPM mechanism produce when running continuously in a laptop?

The 2.5 inch 7200 RPM design emits audible seek clicks and measurable warmth, so the palm-rest area will feel warm after extended use.
