Seagate Surveillance HDD Guide: 500GB to 10TB — Choosing the Right Storage for Your CCTV System

One of the most expensive mistakes in CCTV installations is using a regular desktop or laptop hard disk inside a DVR or NVR. Desktop drives are rated for 8 hours of use per day and designed for occasional read-write operations. A CCTV system writes video data 24 hours a day, 7 days a week, 365 days a year. Desktop drives typically fail within 3 to 6 months in this environment — and all your recorded footage is permanently lost.

Why You Must Use a Surveillance-Grade Hard Disk

Seagate SkyHawk and IronWolf surveillance hard disks are engineered for continuous 24x7 operation. They use CMR (Conventional Magnetic Recording) technology for consistent write performance, include TLER (Time-Limited Error Recovery) for NVR and DVR compatibility, and are rated for up to 550TB per year of workload — more than 3 times the rating of the best desktop drives. This is not optional for a CCTV system: it is the correct and only safe choice.

Recording Duration Calculator: How Long Will Your CCTV Record?

These are real-world estimates for continuous 24x7 recording at 4MP resolution with H.265 compression. For 4 cameras: 500GB gives approximately 7 days, 2TB gives approximately 28 days, and 10TB gives approximately 140 days. For 8 cameras: 500GB gives approximately 3 to 4 days, 2TB gives approximately 14 days, and 10TB gives approximately 70 days. H.265 compression roughly doubles these numbers compared to H.264 — always ensure your DVR or NVR is set to H.265 mode.
