The Seagate ST18000NM004J is an 18TB enterprise-class 3.5-inch SATA hard drive supplied through our wholesale channel for resellers, system integrators, and IT procurement teams building capacity-tier storage. Typical deployment targets include data center bulk storage, object storage platforms, backup and archival systems, and large-scale NAS enclosures. With a 550TB/year workload rating and a security feature set including Instant Secure Erase, it is well suited to racks where reliability and secure decommissioning workflows are procurement requirements. As with all SATA capacity drives, sequential throughput is the strength rather than random IOPS—specify accordingly when matching drives to storage tiers.

Supply & Sourcing Overview
Units are brand new originals sourced through authorized channels, with serial-number verification available on request to confirm original-unit status for your incoming QC process. Stock is held in batch-consistent lots; for volume deployments we can allocate units from a single manufacturing batch and provide consistent firmware revisions across the shipment, simplifying validation and rollout for integrators.
Warranty and RMA handling is managed at the wholesale level: units carry a defined warranty period with a structured RMA process, including advance-replacement options for qualified accounts. Lead times depend on order size—typically ships within 3–7 business days from available stock, with extended lead times quoted in advance for large or batch-specific allocations. All shipments are accompanied by export documentation, and the product carries CE, FCC, and RoHS compliance for international distribution.
This model sits at the high-capacity end of the Seagate enterprise capacity family, delivering the 256 MB cache and 550TB/year rating expected of data center drives rather than desktop-class units. Before placing volume orders, confirm that your backplane, HBA, or motherboard supports SATA 6Gb/s, and that your storage stack supports TCG Enterprise and ISE commands where encryption-based erasure is required. For pricing on volume commitments or batch-specific allocations, request a wholesale quote from our procurement desk.
