ST3250820SCE Seagate DB35 7200.3 0.25TB SATA 8 GB 3.5" Consumer HDD

High-Performance 3.5-inch SATA Hard Disk Drive optimised for continuous write workflows with the ST3250820SCE

The ST3250820SCE is a 3.5-inch SATA hard disk drive designed for systems that prioritise predictable, sustained sequential write behaviour over flash-level latency, making it well suited to single-drive DVR/NVR appliances and legacy SATA server platforms. In rack deployments, the ST3250820SCE integrates cleanly into standard SATA backplanes and controllers, allowing straightforward drive mapping and recovery workflows without specialised NVMe firmware or PCIe topology considerations.

With CMR recording and a 7200 RPM mechanical profile, the ST3250820SCE supports stable write patterns that align with continuous capture pipelines and basic bulk storage tiers. Its onboard cache provides buffering for bursty ingest, while the SATA interface keeps compatibility broad across older chipsets and HBA generations. The ST3250820SCE is most effective when used as a dedicated OS/data disk in legacy nodes, a single-volume video target, or low-capacity cold data where simplicity and deterministic behaviour are preferred.

Why Choose the ST3250820SCE?

The ST3250820SCE delivers a pragmatic density-to-performance balance for SATA environments that require always-on operation and consistent streaming writes. For IT teams maintaining mixed-generation fleets, the ST3250820SCE provides a scalable replacement path across standard 3.5-inch bays, with deployment logic that favours predictable integration, straightforward monitoring, and reliable operation within typical data centre thermal envelopes.

Seagate designs the DB35 series with an engineering focus on steady-state workloads, controlled acoustics, and operational stability, supporting installations that run continuously and must maintain consistent behaviour under sustained activity. This approach aligns with established SATA storage standards and service practices in long-lived infrastructure.

Key Applications:

• DVR and NVR continuous video recording
• Single-drive surveillance capture storage
• Legacy desktop or workstation OS/data drive
• Low-capacity cold data and archival tiers
