160 GB 7200 RPM SATA desktop drive

The Seagate Barracuda 7200.12 ST3160318AS is a 3.5-inch internal hard drive with 160 GB capacity. It spins at 7200 RPM and connects through a SATA 3Gb/s interface with an 8 MB cache. The unit is supplied as a bare drive in new condition.

Suits basic storage upgrades.

This drive suits users adding modest storage to an older desktop or replacing a failed boot drive where a 3.5-inch SATA bay is available. Buyers who want more storage space or faster transfer rates should look at larger or newer drives. The 8 MB buffer and 3Gb/s link limit throughput for demanding workloads.

Steady 7200 RPM operation with 8 MB cache

Under sustained load the spindle maintains 7200 RPM while the 8 MB cache buffers repeated read and write requests. The SATA 3Gb/s interface caps maximum sequential throughput, so performance settles at the link limit rather than peaking in short bursts.

Questions about this item

What type of SATA port and power connector does my motherboard need for the ST3160318AS 3.5" drive?

The drive connects to a standard SATA 3Gb/s data port and requires a 15-pin SATA power connector from your PSU.

Will the 8 MB cache and 7200 RPM speed of this Barracuda 7200.12 drive limit performance on a modern SATA 6Gb/s controller?

The drive negotiates at SATA 3Gb/s, so it runs at its native speed without bottlenecking the faster controller.

How can I confirm the ST3160318AS is recognised at its full 160 GB capacity after installation?

Check BIOS or Disk Management — the drive should report approximately 160 GB and identify as model ST3160318AS.
