ST4000VNA06 Seagate IronWolf Pro 4TB SATA 256 MB 3.5" Server HDD

High-Capacity 3.5-inch NAS HDD featuring SATA integration and 24x7 duty design with the ST4000VNA06

The ST4000VNA06 is a 3.5-inch internal HDD built for NAS and capacity-tier deployments where predictable throughput and sustained availability matter more than low-latency flash. Designed for SMB and branch NAS nodes, the ST4000VNA06 supports always-on file services by combining a 4TB capacity point with a SATA interface that integrates cleanly into standard backplanes, RAID controllers, and HBA-based storage shelves.

Architecturally, the ST4000VNA06 aligns with storage stacks that prioritize efficient caching, sequential transfer, and stable thermal behavior in multi-drive enclosures. A 256MB cache helps smooth bursty I/O from shared folders and media repositories, while 5400 RPM operation targets balanced acoustics, power draw, and long-duration operation. In PCIe-based server platforms, the ST4000VNA06 commonly complements NVMe boot and hot data tiers, providing cost-efficient bulk storage for backups, archives, and large working sets without consuming valuable PCIe lanes.

Why Choose the ST4000VNA06?

The ST4000VNA06 is a pragmatic choice for scaling NAS capacity with consistent fleet behavior across identical SKUs, simplifying spares strategy and RAID set maintenance. The ST4000VNA06 supports dense 3.5-inch bays, enabling strong capacity-per-rack-unit outcomes while keeping power and thermals within typical NAS chassis envelopes for reliable 24x7 service.

Seagate designs IronWolf Pro drives with an engineering focus on sustained operation, workload-oriented tuning, and predictable integration in modern data centre and edge storage standards. This approach supports stable performance characteristics and operational continuity in managed NAS and server storage environments.

Key Applications:

• SMB and branch office NAS
• Always-on file services
• Capacity-tier server storage
• Backup and archive targets
• Workstation bulk data repositories
