I'm moving to a standalone Windows 10 Pro install because unRAID VM was not playing well with my hardware. My goal was to have two 2tb drives acting as a JBOD with a third 2tb drive acting as a parity drive between the two. However, looking at Windows Storage Spaces, it seems that the parity option is striped (and has terrible write performance).
Are there any other Windows-based solutions that can accomplish this? The parity does not have to be calculated and written on the JBOD write. A nightly sync or something along those lines would do nicely.
