Seagate Barracuda 4TB (ST4000DM004) is a desktop-class 3.5-inch internal hard drive that balances high capacity with low power use and quiet operation. With a 4 TB formatted capacity, SATA III (6.0 Gb/s) interface (backward compatible with SATA II/I), a 256 MB multi-segmented cache and a 5400 RPM fluid-dynamic bearing spindle, this Barracuda model is targeted at desktop PCs, all‑in‑one systems, entry-level DAS/home server environments and users who need large, low‑power bulk storage.

The drive delivers sustained transfer rates up to ~190 MB/s (outer tracks), a workload rating around 55 TB/year and high load/unload cycle endurance, making it suitable for mainstream storage, media libraries and backup volumes where quiet operation and energy efficiency matter.
