250 GB 7200 RPM desktop drive

The Seagate BarraCuda 7200.10 ST3250820AS is a 3.5-inch internal hard drive with a 250 GB capacity and a 7200 RPM spindle speed. It connects through a SATA 3.0Gb/s interface and provides an 8 MB cache. Perpendicular recording technology supports the stated capacity and reliability.

Suits legacy SATA builds; not for larger capacities

This drive suits users replacing a failed drive in an older desktop or adding a second SATA volume where 250 GB is sufficient. Buyers who need more than 250 GB of storage should look elsewhere. The bare-drive packaging means no cables or mounting hardware are included.

SATA 3.0Gb/s interface decides compatibility

The single specification that determines whether this is the right part is the SATA 3.0Gb/s interface. The motherboard or controller must provide a matching SATA port for the drive to function.

Questions about this item

Will the SATA 3.0Gb/s interface on this ST3250820AS work with an older motherboard that only supports SATA 1.5Gb/s?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s controllers, so the drive will operate at the slower speed on older motherboards.

How can I verify the 7200 RPM spindle speed and 8.5ms average seek time are performing correctly after installation?

Run the built-in Directed Offline scan diagnostics or use SMART monitoring tools to confirm the spindle speed reports 7200 RPM and seek performance matches the 8.5ms specification.

Since this is a bare drive, what exactly is included and what cables or mounting hardware must I purchase separately?

The box contains only the ST3250820AS drive itself; you will need to buy a SATA data cable, a SATA power connector or adapter, and 3.5-inch mounting screws separately.
