Looks like I purchased my Synology NAS a month early. I recently purchased the Synology 1618+ with 4 8Tb Iron Wolf drives and 32Gb or ram. The problem with the 1618+ is that I have to choose between the 10Gb or NVMe as there is only one slot available. The new 1621XS+ would have been exactly what I was looking for. However the 1618+ has 4 RJ45 ports and I use all 4 using the Layer 2 port channel functionality from my switch and the bonding function of the Synology. I had already configured the switch to use system MTU of 9000. I think what most people do not understand is that 10Gb port on either the 1618+ (adapter card) or the 1621XS+ would normally be used as the single uplink to a network switch, and not to a singe device although this is also possible. I'm currently using the 1618+ as DNS server, Radius server, storage, Plex, and I'm using the Virtual Machine Manager to run a Linux VM hosting OpenDCIM. I'm running Zabbix on a Raspberry Pi and am using that to verify interface utilization along with the information from the port channel information directly from the switch along with the Resource Monitor on the Synology and so far I'm satisfied with the use of the 4 bonded interfaces. My testing included Plex playback, TimeMachine backup (253Gb) via 1Gb wired interface on my Macbook Pro, along with a backup of my Linux server (438Gb) via 1Gb interface at the same time with all the aforementioned Synology services running.
The backups finished in about an hour and fifteen minutes and I did not notice any buffering during the Plex playback. The utilization of the 4 bonded interfaces never crossed 60%. The interfaces on the Macbook Pro and Linux server were of course saturated. At least for the moment I do not need to make the choice between the 10Gb or NVMe.
