No worries at all. I've used TrueNAS before, and you should be fine with adding an ssd pool. That'll work well with a 10GbE connection. :)
There's one thing you might want to try first though, which is to create an iSCSI volume from your hard disk pool and try running your Steam library from that instead of NFS.
iSCSI is a "single user at a time" access thing (unlike NFS), but the caching acts differently to nfs so you might get a better result. Or not. ;)
Am suggesting that as it could be useful to try prior to spending money on ssds. :)
The actual mounting of your TrueNAS iSCSI volume from a Linux box just needs the installation of "open-iscsi" (on Debian anyway).
You run the appropriate iscsiadm command to log in to the iSCSI portal, then mount it:
Heh, and now I just noticed your earlier message had this:
When running games on windows I used iscsi for my games, and that worked well ...
Ahhh well. If you want to try iSCSI for the Linux side of things too, then the above might help. :)
Using an ssd pool on the nas will be your best bet though. With a 10GbE connection it'll feel like a natively attached ssd, which sounds like it'd be a massive improvement for you. :D

Unmounting the iSCSI share afterwards is the standard umount command, then you log out of the iSCSI portal: Anyway, hope that helps. :)
