New homeserver build, which OS?

[shaf]

Hi,

I'm building a new homeserver build and would like some advise on which OS to choose. I'm quite familiar with most of them and just want to make the right choice for my needs.

I currently have an xpenology box which I am replacing and which is running on a 10gbe network.

My use cases are:
Data storage (NAS)
Plex/Media box (no transcoding)
VMs (Ubuntu, Windows).
SSD array for fast read/write
Surveillance software

Choices (and some of my thoughts):

Unraid -
Easy to use, and VMs supported
Nas array will be slow (not raid)

Freenas -
ZFS will be faster
GUI isn't great and is really built for NAS.

xpenology -
Works and reliable.
No support and installing is a pain.


Based on my use cases, which one would you choose? Are there any others I should be looking at?

I think Unraid is top of the list at the moment.

I've read that it does not support SSD arrays or it's not a good idea, is that the case?
What is the best configuration for drives? Mirrored SSD cache or RAID 0 cache? And how big?

Where do you store the VMs on unraid. I usually keep them on an ssd.

I've read that these can be stored on the ssd cache drive?
