SKU CH-EBCM-XZW7Q

160 GB desktop drive at 7,200 RPM with 8 MB cache and SATA 3 Gb/s interface

  • 160 GB capacity stores large media libraries
  • 7200 RPM spindle speed delivers quick data access
  • 8 MB cache buffers frequent read and write operations
  • SATA 3 Gb/s interface connects to mainstream motherboards
  • Native Command Queuing optimises command order for heavier workloads

Product Identity

The Seagate Barracuda 7200.9 is a 160 GB 3.5-inch internal hard drive spinning at 7200 RPM with an 8 MB buffer. It connects through a SATA 3 Gb/s interface that follows the SATA 2.5 revision specification and includes Native Command Queuing. The drive is supplied in new condition.

Ideal Use Cases

This drive suits builders who need a basic SATA hard drive for a desktop PC, a media centre or a legacy server that only accepts 3 Gb/s SATA connections. It is not for buyers who want more storage capacity, faster 6 Gb/s SATA throughput or a solid-state drive for quicker boot times.

Deciding Specification

The SATA 3 Gb/s interface with Native Command Queuing is the single detail that decides compatibility; the motherboard or controller must support this exact standard for the drive to operate correctly.

Questions about this item

How can I verify the ST3160812A is running at 7200 RPM after installation?

Check the drive’s reported rotational speed in BIOS or a SMART monitoring tool; it should show 7200 RPM.

Does the ST3160812A include a SATA data cable and mounting screws, or must I buy them separately?

The drive is supplied as a bare unit; a SATA data cable and 3.5-inch mounting screws are not included and must be purchased separately.

The listing mentions 9BD032-304 — is that a different capacity or just a firmware revision of the 160 GB model?

9BD032-304 is the manufacturer’s part code for this exact 160 GB Barracuda 7200.9 drive; it does not indicate a different capacity.
