Seagate ST4000DM004 – 4TB 3.5-Inch Desktop Hard Drive
The Seagate ST4000DM004 is a 4TB 3.5-inch desktop-class hard drive from the Barracuda compute family, aimed at resellers and integrators supplying cost-sensitive desktop, external enclosure, and light-duty storage builds. With a 5400 RPM spindle and a large 256MB cache, it is positioned for capacity-oriented workloads rather than performance-critical or multi-user NAS applications. Note that desktop Barracuda drives in this class typically use SMR (shingled magnetic recording), which suits sequential write patterns but is a consideration for sustained random-write use cases.
Key specifications (table)
| Parameter | Specification |
| Model | ST4000DM004 |
| Capacity | 4TB (4000GB) |
| Form Factor | 3.5-inch |
| Interface | SATA 6 Gb/s |
| Spindle Speed | 5400 RPM (lower power and acoustics versus 7200 RPM-class drives) |
| Cache | 256MB |
| Data Transfer Rate | Up to 190 MB/s (sequential, outer tracks; guidance only) |
| Power Consumption | Designed for energy-efficient operation |
Good to know
- Uses a standard SATA 6 Gb/s interface and is broadly compatible with desktop motherboards, SATA controllers, and enclosures; confirm firmware/SMR behavior if the target system runs sustained write workloads or ZFS-style arrays.
- Within the Seagate portfolio, the Barracuda line targets desktop/compute storage, while IronWolf is positioned for NAS and SkyHawk for surveillance; Exos covers enterprise capacities — the ST4000DM004 sits in the first category.
- For buying decisions, this drive fits capacity-per-dollar builds (archival, bulk storage, secondary bays); customers needing consistent write performance under multi-stream load should be steered to CMR-based NAS or enterprise SKUs instead.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
