I've recently built a personal server/computer with the intention of having redundancy as the main point for the stored data, with each lettered drive in Windows being in triplicate via RAID 1. My boot drives are M.2 drives with my other storage being SATA III HDDs. Due to X99's lacking support to RAID M.2 drives AT ALL (unless I missed something), I have one M.2 with the system's reserved boot manager partition and Windows 8.1, the 2nd one with Windows 10, the 3rd is untouched, and I have more room that I'm really ever going to use on my zero-redundancy SSDs. The other drives are being managed by Window's data pool thing, and I don't know how good/safe that is.
Would using unRAID allow me to RAID my M.2 SSDs for my desired OS installation setup? If I'm to run Win 10 and 8.1 simultaneously, could I RDP from one into the other to get around needing a 2nd set of peripherals (I have a crossover cable and 2 ethernet ports)? Would using unRAID make it easier for me to allow other people to stream my music and videos without the risk of malware transfer via cross-computer permissions (I don't want Windows to allow any form of writing to my data from my family's not-the-digitally-cleanest computers)?
computer build (relevant parts):
-ASUS X99-E WS/USB 3.1
-i7 6850k
-960 EVO 250 GB (3x; OSs and programs; 2x on PCE card adapters)
-WD Pro 4TB (3x; Steam and pics)
-HGST Ultrastar 8TB (3x; videos; in shipping)
I game on this machine, and if virtualization is to be a thing on this computer, I want to use unRAID, but I'm not sure if I should go for it.
