Seagate Momentus 320 GB 2.5" SATA drive

This Seagate Momentus 5400.6 ST9320325AS is a 2.5-inch internal hard drive with a 320 GB capacity. It connects via a SATA 3 Gb/s interface and spins at 5400 RPM with an 8 MB buffer. The drive is supplied new and is designed for laptop installations.

Ideal for laptop storage upgrades

This drive suits users replacing a failed 2.5-inch SATA drive in an older laptop or adding a secondary drive where a bay is available. It is not for buyers who want more storage capacity than 320 GB. It is not for builders who need a 7200 RPM spindle speed or a 6 Gb/s SATA interface. It is not for systems that require a 3.5-inch form factor.

SATA 3 Gb/s interface constraint

The single specification that decides fit is the SATA 3 Gb/s interface. The host system must provide a compatible 2.5-inch SATA connector running at 3 Gb/s. A laptop limited to SATA 1.5 Gb/s will work but at reduced throughput. A desktop without a 2.5-inch drive bay or adapter cannot accept this drive.

Highlights

  • 320 GB capacity stores large media libraries
  • 5400 RPM spindle balances speed with quiet operation
  • 8 MB cache accelerates frequent file access
  • SATA 3 Gb/s interface fits standard laptop bays
  • New condition ensures full manufacturer reliability
