ST4000VX000 Seagate Surveillance 4TB SATA 64 MB 3.5" Server HDD

High-Density 3.5-inch SATA Surveillance HDD for Continuous Write Workloads with the ST4000VX000

The ST4000VX000 is a 4TB internal 3.5-inch SATA HDD engineered for DVR/NVR platforms that demand predictable 24x7 streaming writes and consistent retention behavior. In surveillance appliances where the CPU and memory subsystem prioritise video ingest, indexing, and network services over compute acceleration, the ST4000VX000 provides a capacity tier optimised for sustained sequential throughput and stable latency under multi-stream camera recording.

Architecturally, the ST4000VX000 uses CMR recording to maintain write determinism during long, uninterrupted capture sessions, reducing the risk of background media management impacting ingest. Its 4Kn media with 512e sector emulation supports broad OS and controller compatibility across legacy and modern SATA backplanes, while the 64MB cache assists with command coalescing and burst absorption typical of edge recording and variable bit-rate streams. The SATA interface enables straightforward integration into PCIe-attached HBAs and storage controllers commonly used in compact NVR servers and dense disk shelves.

Why Choose the ST4000VX000?

The ST4000VX000 delivers a practical density-to-reliability profile for surveillance and other continuous-duty capacity tiers, where the storage layer must remain stable under constant writes rather than short peak transactions. By selecting the ST4000VX000, IT teams standardise on a drive designed for always-on duty cycles, simplifying fleet spares, scaling camera counts through incremental bay expansion, and maintaining predictable retention windows across distributed edge sites.

Seagate designs enterprise-focused HDD platforms with an emphasis on operational continuity, qualification across common storage ecosystems, and consistent behavior under sustained workloads. This approach aligns with modern data centre and edge standards that value serviceability, compatibility, and repeatable performance characteristics in 24x7 deployments.

Key Applications:

• DVR/NVR video surveillance recording
• Multi-stream camera ingest and retention
• Edge recording appliances
• 24x7 SATA capacity tier storage
