The FortiAnalyzer 3750G ingests 8,300 GB of logs per day, sustaining 100,000 logs/sec in analytic mode and 150,000 logs/sec in collector mode, with 24x 16 TB HDD + 4x 15 TB SSD of storage.
8,300 GB/day, 100,000 logs/sec analytic and 24x 16 TB of HDD with 4x 15 TB SSD — the largest FortiAnalyzer, aimed at carriers and very large service providers. At this scale, log architecture is a design exercise: collectors, retention tiering and search behaviour all need scoping before a model is chosen.

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 | 8,300 |
|---|---|
| Analytic sustained rate (logs/sec) | 100,000 |
| Collector sustained rate (logs/sec) | 150,000 |
Hardware
| Total interfaces | 2x 10GE RJ45, 2x 25GE SFP28 |
|---|---|
| Storage capacity | 24x 16 TB HDD + 4x 15 TB SSD |
