ST4000NM003A 4TB SATA 7200RPM 128MB Brand new original
The Seagate ST4000NM003A is a 4TB enterprise-class 3.5-inch SATA hard drive built for 24/7 operation in servers, storage arrays, and high-availability backup targets. Its 7200 RPM spindle and 128 MB cache suit mixed read/write workloads such as NAS, virtualization storage pools, and bulk data archiving. Note that sustained performance depends on the host SATA controller supporting 6 Gb/s to fully realize the interface speed.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Capacity | 4 TB |
| Interface | SATA 6 Gb/s |
| Form Factor | 3.5-inch |
| Spindle Speed | 7200 RPM |
| Cache | 128 MB |
| MTBF | 2 million hours (enterprise reliability rating) |
| Workload Rating | Up to 550 TB/year (guidance for duty-cycle planning) |
| Features | Enterprise-class error recovery, vibration tolerance, 24/7 operation support |
| Condition | Brand new original (confirm warranty terms with supplier before order) |
Good to know
- Uses a standard SATA 6 Gb/s interface, so it integrates with most servers, NAS enclosures, and RAID controllers; verify backplane compatibility for hot-swap bays.
- Compared with nearline/5400 RPM class drives, the 7200 RPM spindle and 128 MB cache provide faster random access, while the 550 TB/year workload rating positions it above desktop-grade drives for continuous-duty environments.
- When ordering for export or volume deployment, confirm firmware requirements and whether your RAID controller requires specific drive qualification before purchase.
