Legacy desktop storage

The Seagate BarraCuda 7200.10 ST3160815AS is a 160GB 3.5-inch internal hard drive built for older desktop systems. It spins at 7200 RPM with an 8MB cache and connects through a SATA 3.0Gb/s interface. The bare-drive package suits repair jobs or capacity upgrades on legacy platforms.

Compatibility check

Verify that the motherboard or controller provides a standard SATA data port and that the power supply includes a SATA power connector. Ensure the chassis has an available 3.5-inch drive bay and mounting screws. The drive is sold as a bare unit without cables, brackets or software media.

Sustained workload behaviour

Under continuous operation the mechanical latency averages 4.16ms while seek and write times sit at 11ms and 12ms respectively. Perpendicular recording technology supports consistent throughput during long copy or backup sessions. The spindle speed and cache size deliver steady performance for archival or secondary storage tasks.
