250 GB 7200 RPM SATA laptop drive
This Seagate Momentus 7200.4 model ST9250410AS is a 2.5 inch internal hard drive with a 250 GB capacity. It spins at 7200 RPM and connects through a SATA 3.0 Gb/s interface with 16 MB cache. The bare drive measures 9.5 mm in height and fits standard laptop bays.
Suits older laptop upgrades and compact storage
Builders refreshing a legacy notebook or needing affordable bulk storage in a 2.5 inch form factor will find this drive appropriate. Buyers who want more storage capacity, a solid-state drive, or a 7 mm z-height for ultra-thin chassis should look at something else.
9.5 mm drive height determines fit
The unit's maximum height is 9.5 mm, which is the critical dimension for compatibility with most traditional laptop drive bays. Systems designed for slimmer 7 mm drives cannot accommodate this model.

Questions about this item
How do I install the 2.5" 9.5mm SATA drive in my laptop?
Slide the drive into the 2.5-inch bay, align the SATA connectors, and secure it with the caddy screws; the step most people miss is forgetting to tighten the caddy screws, leaving the drive loose.
What maintenance or replacement will the 7200 RPM drive need later?
Mechanical drives eventually wear; plan to replace the unit when SMART reports reallocated sectors or seek errors rise, and keep backups current.
What limit appears first during sustained use of the 7200 RPM 16MB cache drive?
The SATA 3.0Gb/s interface caps sustained transfer speed, so long sequential reads and writes will hit that bus ceiling before the platters or cache become the bottleneck.
