Hi guys I have a HP Elitedesk 800 SFF PC with a I5 7500 processor and 16GB DDR4 ram and a m.2 256GB bootdrive. What I want to do is use UNRAID OS and 2 x 8TB 3.5 inch Seagate Ironwolf Pro HDD in raid 1 for media and a expansion PCIe3 for 2 x m.2 2TB for games in raid 0 using it with ISCSI to store and play games from the m.2 drives from my other devices. So my question is it possible to have a raid 1 for media and raid 0 for games to have in this HP Elitedesk and my second question is UNRAID OS good choice for what I want to do or shall I go with TrueNAS OS.
