Designed for legacy SATA desktops

The Seagate ST380811AS is an 80 GB 3.5-inch hard drive built for desktop systems that still use a SATA 3.0 Gb/s connection. It spins at 7200 RPM with an 8 MB cache and includes native command queuing for basic multitasking. The bare-drive packaging suits installers who already have mounting hardware and cables.

Suits older PCs and simple storage tasks

This drive fits machines that need a small, inexpensive SATA volume for an operating system, light applications or secondary file storage. It is not for builders who want more storage capacity, users who need 6 Gb/s SATA throughput, or anyone requiring a modern SSD for boot speed and responsiveness.

The 80 GB capacity decides fit

At 80 GB the drive only accommodates a minimal operating system and a handful of programs before space runs out. Buyers planning large media libraries, game installs or backups must choose a higher-capacity model.

Questions about this item

Does the 3.5" form factor fit a standard desktop drive bay?

The drive uses the standard 3.5" form factor, so it mounts in any desktop 3.5" bay with four screws.

What is the correct way to connect the SATA 3.0Gb/s interface?

Attach the SATA data cable to the motherboard and the SATA power cable from the PSU; no jumper configuration is required for SATA drives.

When should the 80GB drive be replaced?

Replace the drive if SMART tools report reallocated sectors, seek errors, or if the 7200 RPM spindle becomes noisy.
