FortiAnalyzer 300G
100 GB of logs per day, 2,000 logs/sec in analytic mode

The FortiAnalyzer 300G ingests 100 GB of logs per day, sustaining 2,000 logs/sec in analytic mode and 3,000 logs/sec in collector mode, with 2x 4 TB of storage.
100 GB/day and 2,000 logs/sec — four times the 150G on both numbers, which is the right ratio because the two constraints bind together. Storage of 2x 4 TB sets the practical retention limit: at 100 GB/day, that is roughly two and a half months before compression. If your regulator asks for a year, this is not the model regardless of log rate.
Highlights
- 100 GB of logs per day
- 2,000 logs/sec in analytic mode
- 2x 4 TB of onboard storage
- Reporting and retention for PCI DSS, HIPAA and state breach law
Typical deployments
- Mid-size estates with UTM logging enabled
- Deployments where retention is measured in weeks, not years
- Organisations producing regular compliance reporting
What this includes
Fortinet publishes no throughput table for this product — it is licensed per user, endpoint, workload or account. What follows is capability and sizing, not benchmarks.
Capacity
Analytic mode indexes for investigation and reporting; collector mode ingests faster but does not index. Large estates commonly run collectors at the edge feeding one analytic unit at the centre.
| GB logs/day | 100 |
|---|---|
| Analytic sustained rate (logs/sec) | 2,000 |
| Collector sustained rate (logs/sec) | 3,000 |
Hardware
| Total interfaces | 4x GE RJ45 |
|---|---|
| Storage capacity | 2x 4 TB |
