Okay, Roon and any digital system requires three parts. A server, a renderer player and DAC. Any device that is "roon ready" is a renderer player. Additionally, your Lyngdorf has a DAC. You only need a server.
The benefit of a Server is that it insulates the the renderer/player and DAC from the volatility of the internet and also allows access to local files.
My experience is local files can sound better than streamed files. This is especially the case with out a server as a buffer. I find cheap streamers tend to do a poor job of handling internet traffic and local files will sound better.
This is why you get something like a Nucleus. It serves as a server and will get data from Qobuz/Tidal and allow access to any local files. A 2TB SSD stands for two terabyte, solid state drive. SSD means there are no moving parts and they tend to be faster and more stable than traditional hard drives.
The size of the drive is driven by the # of local files you have. I know they were running a promotion with a free 1TB drive recently. If you have a modest library and simply need a few local files, a 1TB drive will be plenty. If you have no local files and only need a backup, then a USB drive or any external USB drive will do the job.
