Seagate 2TB - HDD 3.5" SATA Hard Drives - Ideal for 24/7 continuous recording

2TB Seagate Video 3.5" SATA HDD (ST2000VM003) — the surveillance-class disc built for DVR/NVR write loads rather than desktop duty cycles.

Note the source spec conflict on rotational speed: Seagate's own designation for this line lists 5900RPM, though this listing also states 7200RPM — check the drive label on receipt if speed-matching to an existing RAID or multi-bay recorder.

Key specs

• Capacity: 2TB
• Interface: SATA III, for high-speed transfer between recorder and disc
• Form factor: 3.5" internal HDD
• Target use: CCTV DVR/NVR recording, 24/7 continuous write cycles

Compatibility

Works across DVR and NVR surveillance systems generally, and isn't limited to CCTV — it's also usable in desktops, servers, NAS bays, and external enclosures where a standard 3.5" SATA drive is called for. Useful for installers standardising storage across mixed recorder fleets, or swapping a failed drive without sourcing a different SKU per job.

On the box

Drives are supplied pre-installed and ready to go before dispatch — relevant if you're building out a recorder chassis and want the disc seated rather than shipped loose.

For any multi-drive NVR build, confirm the recorder's maximum supported single-disc capacity and RAID mode against this drive's 2TB size before committing to a fleet order.
