The ST20000NM002D is Seagate’s 20TB Exos-class enterprise HDD, a staple SKU for IT resellers, system integrators, and data center procurement teams sourcing high-capacity SATA storage in bulk. Its 7200 RPM spindle, 256 MB cache, and 550 TB/year workload rating make it a dependable choice for NAS builds, object storage clusters, and backup tiers. For volume orders, batch consistency matters: we can typically supply units from a single manufacturing run with matched firmware, which simplifies fleet imaging and reduces qualification overhead for your deployment pipeline.

Good to know
- Compatibility: fits standard 3.5-inch SATA bays. TCG Enterprise self-encryption and ISE require a host adapter or software stack that supports these features — verify before rollout in security-sensitive deployments.
- Positioning: Exos-class drives carry a higher duty-cycle rating than desktop SATA disks, so they are the correct specification for always-on arrays, not office workstations.
- Transit protection: helium-sealed drives ship in anti-static bags with foam cushioning; bulk cartons and palletized freight are available for container-level orders.
