XCP-NG Build - recommneded SSD/HD size

What is recommended SDD/HD size for XCP-NG server. I want to keep only XCP-NG on it and possibly 1 VM with Xen Orchestra.

Per the wiki, they say 46GB minimum and 70GB recommended. The size of the virtual disk you want for your VM comes into play. A 120 GB SSD might be all you need. However, you may want more.

If you’re really not doing much you can get 250GB SSDs for dirt cheap.
