Seagate ST6000DM003 – 6TB 3.5-Inch Desktop Hard Drive
The Seagate ST6000DM003 is a 6TB 3.5-inch desktop-class hard drive built for bulk storage workloads such as PC internal storage, media libraries, and general desktop NAS enclosures that accept desktop drives. Its 5400 RPM spindle and 128MB cache position it as a capacity-oriented alternative to SSDs, where cost per terabyte matters more than maximum IOPS. Buyers integrating this drive into multi-bay systems should verify vibration tolerance and workload rating against their enclosure’s specifications.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | ST6000DM003 |
| Brand | Seagate |
| Capacity | 6TB (6000GB) |
| Form Factor | 3.5-inch |
| Interface | SATA 6 Gb/s (backward compatible with lower SATA link speeds) |
| Spindle Speed | 5400 RPM (typical for desktop capacity drives; lower acoustics and power than 7200 RPM variants) |
| Cache | 128MB |
| Data Transfer Rate | Up to 180 MB/s (sequential, dependent on workload and system configuration) |
| Power Consumption | Energy-efficient design for desktop use |
Good to know
- As a desktop-class (Barracuda family) drive, it is intended for single-user and light multi-user workloads; for 24/7 NAS use consider IronWolf, for surveillance SkyHawk, and for datacenter workloads the Exos line — workload rating and warranty terms differ across these series.
- The 5400 RPM, 180 MB/s sequential profile suits capacity-first applications (archiving, backups, media storage); latency-sensitive databases and virtualization workloads are better served by 7200 RPM enterprise drives or SSDs.
- Before ordering, confirm your chassis/enclosure accepts 3.5-inch SATA drives and check current stock conditions with your account manager, as desktop 6TB SKUs in the Huaqiangbei market vary in sourcing channel and remaining manufacturer warranty coverage.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
