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

The single most common reason for CCTV system failure in Chennai is a failed hard disk. Not the camera. Not the DVR. The hard disk — specifically, a desktop drive used in a 24/7 recording environment it was never designed for. Seagate's surveillance-grade hard disk range is the solution, engineered from the chip up for the unique demands of continuous video recording.

Why Desktop HDDs Fail in CCTV Systems

Desktop hard disks are rated for 5 to 8 hours of daily operation. A CCTV system records 24 hours a day. Within 3 to 6 months, a desktop drive in a DVR or NVR will overheat, generate read/write errors, and eventually fail — taking every recording with it. Surveillance hard disks are rated for continuous 24/7 operation with workload ratings measured in hundreds of terabytes per year.

Which Seagate HDD Should You Buy?

• 500GB (₹2,300): For 2–4 cameras at 1080p H.265 — approximately 7 days recording. Best for budget installations.

• 2TB (₹7,750): For 4–8 cameras at 1080p H.265 — approximately 28 days recording. The most popular choice.

• 10TB (₹42,000): For 8–16+ cameras at 4MP H.265 — approximately 45–80 days recording. For large commercial sites.

Seagate 10TB Key Advantages

• All-CMR recording technology — no write throttling, consistent performance

• Workload rating of 550TB per year — highest in its class

• 5-year limited warranty — longest surveillance HDD warranty available
