I am looking to use unRAID strictly for VM purposes, I've been told it's a solution to a problem I have. I currently have a 1TB NVME drive that I was going to partition and dual boot Windows 10 and OS X, but I've been told unRAID can accomplish this by just using two VM's and I wouldn't have a performance hit. Can I use unRAID with just one NVME and run both VM's? I have two 500GB SSD's I kind of wanted to use for a larger storage, but that can come later, the 1TB is enough for my immediate needs.
