In 1600 / 1800 Appliance R80.20.XX Getting Started Guide we find details about interface speeds and specifications of the new models:
The 1600 adds a second WAN port and changes DMZ and WAN port to a combo port of SFP and RJ45 (SFP or RJ11 can be used) for up to 1000MbE. The LAN ports 1-16 support 10/100/1000MbE, LAN 1 and LAN 2 (Sync) also support 2.5GbE.
The 1800 has SSD storage (capacity?) and two redundant PSUs added to hardware. Most unusual: DMZ combo RJ45 port supports 10/100/1000/2500/5000MbE and 10GbE, SFP port supports 10GbE. The LAN ports 1-18 support 10/100/1000MbE, LAN 1 and LAN 2 (Sync) also support 2.5GbE. And we have a Management port that supports 10/100/1000MbE.
So my question is: We can use the 1800 DMZ port for 10GbE connection to the internet, and we even have LAN1 and LAN2 ports with 2.5GbE - but both WAN IFs are limited to 1000MbE. If the DMZ contains a server that is used very frequently from internal networks, it also would make sense to use it that way. But on 1600 only LAN 1 and LAN 2 support 2.5GbE, all other prts are limited to 1000MbE.
Any comments on the design decisions ?
