Drive Profile

The Seagate Momentus Thin ST320LT007 is a 2.5-inch laptop internal hard drive with a 320GB capacity and a 7mm z-height. It spins at 7200 RPM with a 16MB cache and connects via a SATA 3.0Gb/s interface. The slim form factor fits thin ultraportables and mainstream notebooks that require a 7mm drive bay. This bare drive unit is supplied new without retail packaging.

Fit and Limits

This drive suits owners upgrading older SATA laptops or netbooks that accept a 7mm 2.5-inch drive and need modest capacity for an operating system and everyday files. Builders working with modern systems that only provide M.2 slots or require higher capacities should look elsewhere, as this unit uses the legacy SATA interface and offers 320GB of storage.

Deciding Spec

The 7mm height is the critical dimension; it matches the slim drive bays found in many thin-and-light notebooks and is also compatible with standard 9.5mm bays. Verify the laptop's drive bay height and SATA interface before purchase to ensure physical and electrical compatibility.

Questions about this item

How do I confirm the ST320LT007 is running at 7200 RPM after installation?

Check the drive information in your BIOS or a utility such as CrystalDiskInfo; the reported rotation speed should read 7200 RPM and the interface speed 3.0 Gb/s.

The listing says Bare Drive — does the box include mounting screws, a SATA cable or a caddy, and what must I source myself?

Bare Drive means only the 2.5-inch 7mm unit is supplied; you will need to provide any mounting screws, SATA data cable and drive caddy or bracket required by your laptop.

I see the 320GB 7mm Momentus Thin — are there other capacities or heights in this series that I should consider instead?

This product page covers the single 320GB 7mm model; other capacities or 9.5mm variants are separate part numbers not listed here.
