Capacity and interface

The Seagate ST3250620AS is a 250GB 3.5-inch internal hard drive using a SATA 3.0Gb/s connection. It suits desktop builders adding bulk storage for documents, media or backups where solid-state speed is not required. The bare-drive packaging means no cables or brackets are included.

Sustained workload behaviour

A 7200 RPM spindle and 16MB cache deliver consistent throughput for sequential reads and writes during long copy jobs. Average seek time of 8.5ms and latency of 4.16ms keep access steady rather than spiking under load. Perpendicular recording helps maintain data integrity across extended write sessions.

Build and daily implications

Enhanced G-Force Protection guards the mechanism against knocks during installation or case moves. Whisper-quiet operation keeps acoustic output low in a typical tower. The standard SATA data and power connectors fit any modern desktop motherboard and power supply without adapters.
