Product identity

This is a new Seagate Barracuda 7200.9 internal hard drive with an 80 GB capacity and a 3.5 inch SATA 3Gb/s interface. It spins at 7200 RPM and includes an 8 MB cache buffer. The drive suits desktop PCs that require a basic mechanical storage device.

Suitability and limits

Buyers who want more storage or a faster interface should look elsewhere. Systems without a SATA port or without a 3.5 inch drive bay cannot use this unit. Laptop builders and compact chassis that only accept 2.5 inch drives will need a different form factor.

Deciding specification

The 3.5 inch SATA 3Gb/s interface determines whether the drive fits the motherboard and chassis. Verify that the host has a matching SATA connector and a standard 3.5 inch bay before purchase.

Questions about this item

Will the 3.5 in SATA 3Gb/s drive fit a standard desktop 3.5 in bay?

Yes, the 3.5 in form factor matches standard desktop drive bays and uses the SATA 3Gb/s interface for power and data connections.

What is the correct way to install the ST3808110AS and what step is often missed?

Secure the drive with four screws in the 3.5 in bay, attach the SATA data cable to the motherboard and the SATA power cable from the PSU, then ensure the drive is enabled in BIOS — the step often missed is entering BIOS to confirm detection.

How long can the 80GB 7200RPM drive with 8MB cache run before it typically needs replacement?

Mechanical drives like this 7200RPM model have moving parts that wear over time; plan to replace after three to five years of regular use or if SMART data shows reallocated sectors.
