Thanks to both Peter and Cooper! 

I do split out by event type already and I can certainly trim out some of this if needed. Ill let you know how it goes.

Hi All, 

I am looking for advice. We are working on setting up a machine for potential 40GB a second on inspection. Our concern comes in the write speed of the I/O to disk as the meta-data that Suricata creates is important to us. Does anyone have experience with this? I have listed some of our set up below. Are there any suggestions or known issues that I should be aware of. 

My five cents to start with: 
I would split the logging per event_type and only log what is needed not just everything as some logs depending on the traffic could be very very verbose- like dns/fileinfo on university network etc.. 
Also filter out if possible with a bpf(or on the mirror /tap) what is not relevant too. 


DL360 Gen 10 
P408I-A (Raid Card) 
4 x 2TB SSD in RAID 10 (Part number 877788-B21) 
Mixed use SSDs
