1TB Hard Drive Price: 3.5" SATA HDDs for CCTV Recorders

This range covers four 1TB hard disk drives (HDDs). Each is a 3.5" SATA model, and each listing describes it as suited to 24/7 continuous recording. Two are Seagate, one is Western Digital Green Power, and one is listed without a brand name.

A 1TB drive stores footage from a digital video recorder (DVR) or network video recorder (NVR). "1TB" means one terabyte of capacity. "SATA" is the connection type between drive and recorder. "3.5 inch" is the physical size, so the recorder needs a bay and connectors to match.

How to choose

• Recorder fit: check that your recorder takes a 3.5" SATA drive. Also check the maximum drive size it supports.
• Capacity: how long 1TB lasts depends on camera count, resolution and recording mode. More cameras or sharper images fill it sooner. Recording only on motion stretches it further.
• Brand: the range offers Seagate, Western Digital Green Power or an unbranded option. The listings share the same headline spec, so compare the individual product pages.
• Retention: if you need a longer history than 1TB gives, look at larger capacities elsewhere in Storage.

Fitting is a small job. Power the recorder down, mount the drive, connect the data and power leads, then format it from the recorder's menu.
