Seagate Momentus 5400.3 160GB 5400RPM 2.5" SATA internal hard drive

SKU CH-JNNC-AX5CS

A 160 GB 2.5-inch SATA laptop drive spinning at 5400 RPM with 8 MB cache

  • 160 GB capacity stores large media libraries
  • 5400 RPM spindle speed delivers steady read performance
  • 8 MB cache buffer accelerates frequent data access
  • SATA 1.5 Gb/s interface connects to most laptops
  • 5 inch form factor fits standard drive bays

Capacity and form factor

The Seagate Momentus 5400.3 is a 2.5 inch SATA hard drive with 160GB of storage. It is built for laptops or compact desktops that accept a 2.5 inch bay and a SATA 1.5Gb/s connection. The 5400RPM spindle speed and 8MB cache suit everyday office work and light media playback.

Real-world headroom

The 160GB capacity holds a basic operating system, productivity applications and a modest document library. Large game installations, video editing projects or extensive media collections will exceed the available space quickly. The 5400RPM mechanism and 1.5Gb/s interface limit sustained transfer rates, so heavy random workloads feel sluggish compared to modern solid-state drives.

Included identifiers

The drive ships as a bare unit identified by model number ST9160821AS and part number 441128-001. No mounting brackets, cables, cloning software or adapter hardware are mentioned in the supplier data. Installers must provide any required SATA data cable, power connector or drive caddy separately.

How can I confirm the ST9160821AS is running at its rated 5400RPM after installation?

Use a SMART monitoring tool such as CrystalDiskInfo to verify the rotational speed reads 5400 RPM and the drive health status shows Good.

Does the Momentus 5400.3 come with a mounting bracket or SATA cable for a desktop build?
