Why do Synology NAS have 2 ethernet connections ?

Seriously curious.

redundancy, increased bandwidth.

Ok thank you.

Multi use.

Mine has 4.
Port 1- NAS network 1
Port 2- NAS network 2
Port 3- iSCSI-1
Port 4- iSCSI-2 (iSCSI multipath/round robin).

Heck, my home-built NAS has 4 for the same reason.

As mentioned, its for redundancy or performance (or both!):

It's already been answered, but I'll add 2 more cents. Pretend the NAS isn't for home, but for a business. They would have redundant switches too. So one port into each switch. Even if you don't need the speed with LAG, you can get redundancy.
