Estimates based on H.265 compression at 15fps. H.264 requires ~40% more storage. Higher fps increases storage proportionally.
Key Variables
- Codec: H.265 saves ~40% vs H.264
- Frame rate: 15fps is standard; 30fps doubles storage
- Quality: Higher bitrate = larger files
- Motion sensitivity: More triggers = more recording
- Pre/post buffer: Adds to each clip
Blue Iris Storage Configuration
Optimal Drive Setup
The Blue Iris community recommends separating OS and recording storage:
| Drive | Purpose | Recommendation |
|---|---|---|
| Boot Drive (C:) | Windows + Blue Iris software | 256GB+ SSD (NVMe preferred) |
| Database Drive | Blue Iris database + alerts | Same SSD or separate small SSD |
| Recording Drive (D:) | Video storage | WD Purple 8TB+ |
Why separate drives?
- SSD handles random I/O for UI responsiveness
- HDD handles sequential video writes efficiently
- Prevents OS slowdowns during heavy recording
- Allows independent upgrades
Blue Iris Settings for Drive Longevity
Optimize Blue Iris settings to extend drive life:
- Direct-to-disc: Enable to reduce memory buffer writes
- BVR format: Blue Iris's native format is more efficient than MP4
- Limit clips folder: Set maximum size to prevent drive overfill
- Automatic overwrite: Enable to cycle old footage
- SMART monitoring: Enable alerts for drive health
RAID Considerations for Blue Iris
Do You Need RAID?
For most home Blue Iris users, RAID is not necessary:
- Surveillance footage has limited retention value
- Single drive simplifies setup and troubleshooting
- Modern surveillance drives have excellent reliability
- RAID adds cost and complexity
When RAID Makes Sense
- Business/legal requirements: Footage must not be lost
- Large systems: 16+ cameras with long retention
- Critical applications: Evidence preservation required
RAID Recommendations
If you do implement RAID:
| RAID Level | Drives | Usable Space | Fault Tolerance | Best For |
|---|---|---|---|---|
| RAID 1 | 2 | 50% | 1 drive | Simple redundancy |
| RAID 5 | 3+ | 67-90% | 1 drive | Balanced performance/redundancy |
| RAID 6 | 4+ | 50-75% | 2 drives | Maximum protection |
| RAID 10 | 4+ | 50% | 1 per mirror | Performance + redundancy |
Important: Use identical drives for RAID. Mixing brands or capacities can cause issues.
