Do I need to add SSD?
-
I'm considering to buy SG-3100. If I don't use cache proxy and only use IDS, DHCP, OpenVPN, DDNS and NAT, is it OK to just use 8GB MMC?
-
Yes.
The Snort/Suricata rules can take some space but nothing that would be a problem there. The logs are usually what uses more than intended. But as long as you check they are rotating as expected after installing it should be fine.

indeed, there is also an option for suricata and snort
Log Directory Size Limit -> Enable Directory Size Limit
if you set this you are sure that logs will not overwhelm your system

Thanks for your comments.
I got it last Friday. I stream all pfsense log file to rsyslog in my Dell T20 home server. That solved the log problem.
I got all my need. Now it only use 15% of 6.9GiB of disk.

@rickyzhang I purchase an M.2 32GB and reinstalled PFsense on it, because the wear of eMMC
-
I didn't look into eMMC inside my SG-3100. I'm not sure if it has level wearing or not.
But in general, if I only use less than 20% space and streams the log file to other place, I bet it can last for very long.
Let's do an experiment. We will see who will last longer 5 years from now.
