The FortiAnalyzer 3100G ingests 3,000 GB of logs per day, sustaining 42,000 logs/sec in analytic mode and 60,000 logs/sec in collector mode, with 16x 4 TB HDD + 2x 1.92 TB SSD of storage.
3,000 GB/day with a hybrid 16x 4 TB HDD plus 2x 1.92 TB SSD layout — the SSD tier is what keeps search responsive at this volume, and it is the reason this is not simply a bigger 1000G. At three terabytes a day, retention arithmetic dominates the purchase: multiply your regulatory requirement by daily volume before comparing models.

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 | 3,000 |
|---|---|
| Analytic sustained rate (logs/sec) | 42,000 |
| Collector sustained rate (logs/sec) | 60,000 |
Hardware
| Total interfaces | 2x GE RJ45, 2x 25GE SFP28 |
|---|---|
| Storage capacity | 16x 4 TB HDD + 2x 1.92 TB SSD |
