Seagate BarraCuda 7200.9 ST3250824AS 250GB 7200 RPM 8MB SATA 3.0Gb/s 3.5" internal hard drive

Desktop storage for everyday workloads

The Seagate BarraCuda 7200.9 ST3250824AS is a 250GB 3.5-inch internal hard drive built for desktop PCs that need reliable capacity at 7200 RPM. It connects through a SATA 3.0Gb/s interface and includes an 8MB cache with native command queuing for smoother multitasking. This bare drive suits system builders and upgraders who want straightforward mechanical storage. It is not for users who require solid-state speeds or capacities above 250GB.

Thermals noise and power in typical use

The drive spins at 7200 RPM with average seek of 8ms, write of 9ms and latency of 4.16ms, figures that reflect standard desktop mechanical operation. Seagate highlights whisper-quiet acoustics and a rugged, efficient design that keeps heat and noise low during normal workloads. Best-in-class shock resistance protects data whether the system is running or powered off. No power-draw numbers are provided so exact thermal output cannot be stated.

What the bare-drive package changes

Supplied as a bare drive without cables, mounting hardware or software, the ST3250824AS requires the installer to provide SATA data and power leads plus any bracket needed for the chassis. The absence of bundled utilities means drive management relies on the operating system or third-party tools. RoHS compliance confirms restricted-substance adherence but adds no functional feature for the end user.
