1TB CCTV hard drives
A 1TB hard drive gives you roughly one terabyte of storage dedicated to recording video from your CCTV system. This range covers 3.5" SATA drives designed to run continuously, which matters because CCTV recording is a much heavier, more constant workload than typical desktop PC use.
All four drives here are 3.5" SATA units aimed at CCTV recorders (DVRs/NVRs), described as suited to 24/7 continuous recording. Options include Seagate drives and a Western Digital Green Power drive, alongside an unbranded 1TB option.
How to choose
- Recorder compatibility: check your DVR/NVR's supported drive interface and maximum capacity before buying — a 3.5" SATA drive is the standard fit for most CCTV recorders, but always confirm against your recorder's manual.
- Recording workload: 24/7 continuous recording writes constantly, so a drive rated for that kind of sustained use (as these are described) suits CCTV better than a general-purpose drive.
- Capacity vs. camera count: 1TB suits fewer cameras or shorter retention periods; more cameras, higher resolution, or longer retention will use up storage faster.
- Brand preference: choose between Seagate, Western Digital, or the unbranded option based on what you're comfortable with — all are positioned for the same continuous-recording use case.
1TB — frequently asked questions
Will a 1TB drive fit my CCTV recorder?
These are 3.5" SATA drives, the standard interface for most CCTV DVRs/NVRs, but you should always check your specific recorder's supported drive size and maximum capacity first.
How much CCTV footage can 1TB store?
This depends on your camera count, resolution and how long you want to keep footage, so retention time varies a lot between setups — check your recorder's estimate tool or manual if it has one.
