Storage spaces is probably the best software raid available today. Unfortunately, it comes with windows.
It supports heterogenous drives, safe rebalancing (create a third copy, THEN delete the old copy), fault domains (3-way mirror, but no 2 copies can be on the same disk/enclosure/server/whatever), erasure coding, hierarchical storage based on disk type (e.g., use NVMe for the log, SSD for the cache), clustering (paxos, probably). Then you toss ReFS on top, and you're done.
The only compelling reasons to buy windows server are to run third party software or a storage spaces/ReFS file share.
