Purpose and audience

The Seagate BarraCuda 7200.9 ST3808110AS is an 80GB desktop hard drive built for legacy SATA systems. It suits repair technicians, retro enthusiasts or anyone extending an older PC that still relies on the 3.0Gb/s interface.

Build and connectivity

The bare 3.5 inch unit measures 1.0 inch high and connects through a standard SATA 3.0Gb/s port with NCQ support. A 3-D Defense System and shock ratings of 63 Gs operating and 350 Gs non-operating protect the platters during handling and daily vibration.

Thermals noise and power

Spindle speed runs at 7200 RPM with an average latency of 4.16ms and 8MB cache. The mechanical design targets typical desktop thermal and acoustic levels for a drive of this class, drawing power only from the SATA connector during normal operation.

Questions about this item

Does the SATA 3.0Gb/s interface on the ST3808110AS limit real-world transfer speeds?

The 3.0Gb/s SATA link sets the maximum bus bandwidth for this 80GB drive; actual throughput depends on the 7200 RPM platters and 8MB cache.

What physical space and mounting does the 3.5" 1.0-inch drive require?

It fits a standard 3.5-inch bay with 1.0-inch height and uses the usual four side-mount screw holes.

How is the bare ST3808110AS installed, and what step is often missed?

Connect the SATA data and power cables, secure the drive with four screws, then initialise and format it in the operating system — the formatting step is frequently overlooked.
