11th-generation 160GB desktop drive

The Seagate BarraCuda 7200.11 ST3160813AS is a 3.5-inch internal hard drive built for desktop computers that need a 160GB capacity at 7200 RPM. It suits system builders and upgraders who want a straightforward SATA 3.0Gb/s drive for an operating system, applications or bulk files. Buyers who need more storage space or a faster solid-state interface will not find that here.

SATA 3.0Gb/s bare-drive integration

This bare drive connects to any motherboard or controller with a standard SATA 3.0Gb/s port and draws power from a conventional SATA power connector. No mounting rails, cables or adapter brackets are included, so the builder must supply those parts. The 3.5-inch form factor fits typical desktop drive bays and frees up 2.5-inch slots for other devices.

7200 RPM sustained throughput

A 7200 RPM spindle speed and 8MB cache combine with second-generation perpendicular recording to maintain consistent data rates during extended read and write sessions. Average latency of 4.16ms supports steady performance for long file transfers, backups or video capture without the slowdown that can appear on lower-speed drives.
