Thin laptop drive for storage upgrades
The Seagate Momentus Thin ST320LT009 is a 2.5 inch internal hard drive built to a 7.0 mm height. It fits notebooks that require a slim profile while retaining a standard SATA 3.0Gb/s interface. The bare drive arrives without cables or brackets for direct installation.
320GB capacity with 7200 RPM speed
The drive provides 320GB of storage and spins at 7200 RPM with a 16MB cache for responsive access to operating systems and applications. Performance scales with the SATA 3.0Gb/s link, so sustained transfers will not exceed that interface bandwidth. Heavy media libraries or large game collections will fill the available space quickly.
7mm form factor works in 9.5mm bays
The 7.0 mm z-height allows installation in ultra-thin laptops and also seats correctly in standard 9.5mm drive bays. SmartAlign technology handles the transition without jumpers or adapter frames. A Self-Encrypting Drive option with TCG Opal and FIPS 140-2 validation is available for environments that require hardware encryption.

Questions about this item
Will the 7.0 mm height fit in my older laptop that only accepts 9.5 mm drives?

Does the bare drive include mounting screws or a SATA cable for installation?
No, the bare drive package contains only the hard drive; screws and cables must be sourced separately.
