While watching Linus' Gaming PC and NAS in one tower video today I got to thinking about how I could build a similar setup. What I am really wanting is Unraid to power my plex sever (which it can do using docker) with what would be 3 or 4 4TB drives in a RAID 5 while the OS is running in a RAID 0 on 2 Samsung 850 EVO's. In the video he uses 2 1TB SSD's for the cache, but what can be stored on the cache? That is just for data that is going to be written to the array correct? I want SSD performance out of my OS but if the OS cannot sit on the cache would I need a completely separate array of SSD's just to handle the OS?
I'm relatively new to the VM world so any help is appreciated.
