Silver 2.5 inch SATA internal hard drive with exposed circuit board

Seagate

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.

商品問答

Will the 1.5Gb/s SATA interface on this 160GB drive work with an older laptop that only supports SATA 1.0?

Yes, the SATA 1.5Gb/s interface is backward compatible with first-generation SATA controllers found in older laptops.

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?

The drive is supplied as a bare 2.5-inch unit; a 2.5-to-3.5-inch adapter bracket and a standard SATA data cable must be purchased separately for desktop use.
