Product Description
Seagate Barracuda 1TB (ST1000DM010) — what it's for
This is a 3.5-inch SATA III hard drive for storing footage inside a DVR or NVR recorder, or a PC. It runs at 7200 RPM with a 64 MB cache, which keeps write speeds steady when a recorder is writing multiple camera streams continuously.
Why this matters for CCTV
Recording 24/7 puts constant read/write load on a drive, unlike normal desktop use. A drive rated for continuous operation is less likely to struggle under that pattern, and the Barracuda's SATA III interface and 7200 RPM speed are built for sustained data transfer rather than occasional bursts.
Where it fits
- Interface: SATA III — check your recorder has a free SATA bay before ordering.
- Form factor: standard 3.5-inch, fits desktop-style drive bays.
- Compatible with: DVR and NVR surveillance systems, plus desktops, servers, NAS units and external enclosures.
- Capacity: 1TB — fine for shorter retention periods or fewer cameras; higher-resolution or multi-camera setups will fill it faster.
The drive arrives fully installed and ready to fit, so there's no need to format or configure it yourself before dropping it into your kit.
Before you buy
Check your DVR/NVR's maximum supported drive capacity and interface type in its manual — not every recorder accepts every drive size.
