When setting up a surveillance system, choosing the right security camera hard drive is critical for reliable, 24/7 recording. Seagate’s enterprise-grade drives, like the SkyHawk series, are engineered specifically for high-load video workloads. But with multiple options available, how do you select the ideal drive for your needs? Let’s break down the essentials.
1. What Makes a Security Camera Hard Drive Different?
Unlike standard hard drives, security camera hard drives (e.g., Seagate SkyHawk or SkyHawk AI) are optimized for continuous writing. Key differences include:
- Workload Rating: SkyHawk drives support up to 180TB/year workload (vs. 55TB for consumer drives).
- Vibration Resistance: Built to handle multi-bay NVR environments with minimal performance drop.
- Firmware: Includes ImagePerfect™ firmware to reduce frame loss during high-resolution recording.
For 2025, Seagate’s latest SkyHawk AI 18TB (ST18000VE002) leads the market with 550MB/s sustained throughput, ideal for 64-channel AI-powered surveillance.
2. How Much Storage Do You Need for 24/7 Recording?
Storage requirements depend on camera resolution, compression (H.265 vs. H.264), and retention period. Here’s a quick reference:
| Resolution | H.264 (GB/day) | H.265 (GB/day) |
|---|---|---|
| 1080p | 60 | 30 |
| 4K | 240 | 120 |
For a 16-camera 4K system with 30-day retention, H.265 requires at least 16TB (120GB × 16 × 30). Always allocate 20% extra for metadata and system files.
3. Can You Use NAS or SSD Drives for Surveillance?
While NAS drives (like Seagate IronWolf) offer reliability, they lack surveillance-specific optimizations. SSDs, though faster, are cost-prohibitive for long-term storage. Key comparisons:
- NAS Drives: Higher random I/O but lower write endurance than SkyHawk.
- SSDs: Suitable for edge recording (e.g., 4K body cams) but degrade faster under constant writes.
For most setups, enterprise surveillance HDDs remain the practical choice.
