ST20000NM002D 20TB SATA 7200RPM 256MB Brand new original
The Seagate ST20000NM002D is a 20TB 3.5-inch enterprise hard drive from the Exos family, aimed at system integrators, data center operators, and bulk IT resellers building capacity-oriented storage. With a SATA 6 Gb/s interface, 7200 RPM spindle, and a 550 TB/year workload rating, it suits NAS, object storage, backup tiers, and other high-capacity sequential workloads. Note that real-world sustained throughput depends on the host controller and workload mix, so validate against your application profile before large-volume deployment.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | ST20000NM002D (Seagate Exos family) |
| Capacity | 20 TB |
| Interface | SATA 6 Gb/s |
| Form Factor | 3.5-inch |
| Spindle Speed | 7200 RPM |
| Cache | 256 MB |
| Workload Rate | Up to 550 TB/year (annualized, guidance for duty-cycle planning) |
| MTBF | 2.5 million hours (rated, not a guarantee of field life) |
| Security Features | Seagate Secure™, Instant Secure Erase (ISE), TCG Enterprise encryption support (requires compatible host/management software) |
| Reliability | Helium-sealed design for low friction and consistent performance |
| Power Efficiency | Optimized for reduced power consumption per TB |
| Condition | Brand new original |
Good to know
- Compatibility: standard 3.5-inch SATA drive bay; TCG Enterprise self-encryption and ISE require a host adapter or software stack that supports these features — confirm before deployment in security-sensitive environments.
- Family positioning: as an Exos-class enterprise drive, it carries a higher workload rating (550 TB/year) than typical desktop-class SATA disks, making it the appropriate choice for always-on NAS and data center arrays rather than office PCs.
- Buying tip: when ordering in volume, request consistent firmware and single manufacturing batch where possible to simplify fleet imaging, and verify packing (anti-static bag + foam) to protect helium-sealed drives in transit.
