Surveillance Hard Drives 1TB – CCTV Trade Supply
4 products in our Storage range — trade-grade UK stock from CCTV Line.
1TB 3.5" SATA hard drives sized for continuous CCTV recording. This range covers four 1TB drive listings — two Seagate 1TB models, a Western Digital Green Power 1TB, and a further unbranded 1TB 3.5" SATA option — all positioned for 24/7 DVR/NVR duty rather than desktop use.
What's in the range
- 3.5" form factor, SATA interface — fits standard DVR/NVR internal drive bays.
- 1TB capacity point — an entry-level tier for shorter retention or lower channel counts.
- Marketed for continuous recording workloads rather than intermittent PC use.
How to choose
- Brand preference/compatibility: Seagate (two listings), Western Digital Green Power, or the unbranded option — check your recorder's compatibility list or existing drive brand if replacing a failed unit.
- Retention needs: 1TB is the smallest capacity in the Storage range; estimate your required days of footage against channel count and resolution before committing, and step up to a larger capacity tier if you need longer retention.
- Replacement vs new build: for an existing system, matching the installed drive's brand and firmware behaviour can simplify RAID or NVR pairing.
All four are aimed at continuous-write CCTV use rather than general-purpose storage, so treat this tier as the baseline capacity option in the Storage category.
