160GB 7200RPM Desktop SATA Hard Drive

The Seagate Barracuda 7200.10 ST3160815AS is a 3.5 inch internal hard drive with 160GB capacity. It spins at 7200RPM and connects via a SATA 3Gb/s interface with an 8MB cache buffer. This drive is built for standard desktop storage tasks.

Suits older desktop upgrades and light storage

This drive suits users replacing a failed drive in an older desktop or adding basic secondary storage for documents and backups. It is not for buyers who need more storage capacity or faster transfer speeds for modern workloads. Builders requiring a 6Gb/s SATA interface should look at other options.

The SATA 3Gb/s interface decides compatibility

The single specification that decides fit is the SATA 3Gb/s interface, which must match the motherboard or controller port available in your system. The drive also requires a standard 3.5 inch drive bay and SATA power and data cables for installation. Verify these connections before purchase.

Questions about this item

How does the 3 Gb/s SATA interface on the ST3160815AS work with an older motherboard SATA port?

The drive uses the SATA 3 Gb/s interface which is backward compatible with earlier SATA revisions, so it will operate at the speed the motherboard port supports.

What should I check to confirm the ST3160815AS is running correctly after installation?

Verify the drive appears in BIOS with the correct 160 GB capacity, listen for normal 7200 RPM spin-up sounds, and run the manufacturer diagnostic tool to confirm the 8 MB cache and SMART status report no errors.

What comes with the ST3160815AS and what must I provide separately?

The box contains the bare 3.5 inch SATA hard drive only; you will need to supply a SATA data cable, a SATA power connector from your power supply, and mounting screws for your case.
