Momentus 7200.3 80GB Laptop Drive

The Seagate Momentus 7200.3 ST980411AS is a new 2.5-inch internal hard drive with 80GB capacity and a 7200 RPM spindle speed. It connects via a SATA 3.0Gb/s interface and includes 16MB of cache for improved data access. This bare drive is designed for notebook computers requiring a standard SATA storage device.

Suits older laptop upgrades and repairs

This drive suits users upgrading or repairing older laptops that accept a 2.5-inch SATA hard drive with a 3.0Gb/s interface. The 7200 RPM speed and G-Force Protection feature support mobile use where mechanical shock resistance is valued. Buyers needing larger capacities, solid-state speeds, or a newer SATA 6.0Gb/s interface should look at alternative storage options.

SATA 3.0Gb/s interface determines compatibility

The single specification that decides fitment is the SATA 3.0Gb/s interface combined with the 2.5-inch form factor. Verify that the target notebook uses this exact interface revision and physical size before purchase. The 16MB cache and 4.17ms average latency are secondary characteristics that follow from the drive’s core design.

Questions about this item

How much power and heat does the 7200 RPM Momentus 7200.3 produce when running continuously in a laptop?

It uses Seagate laptop power management technology to deliver the lowest-power 7200-RPM drive, and ramp load features remove the head during idle periods to cut idle power consumption and heat.

What laptop interface and form factor are required to install the ST980411AS?

The drive needs a 2.5-inch bay and a SATA 3.0Gb/s connection; it is a bare drive without brackets or cables.

Will the SATA 3.0Gb/s ST980411AS work alongside an older SATA 1.5Gb/s drive in the same machine?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s controllers, so it can operate alongside older SATA drives.
