Why Choose the 81F Over the 80F?
The primary difference between the 80F and 81F is the integrated 128GB SSD on the 81F. This makes the 81F ideal when:
-
Local logging is required
-
You plan to store analytics or reports locally
-
You want added flexibility for advanced services
If you do not need onboard storage, the 80F provides the same security performance without SSD.
