I keep seeing 3.8TB Intel D4502 nvme drives on ebay...cheap. $3-500. These are Dual Port NVME and need a dual port backplane, etc to work. I have looked around but have not found any machines or parts with this as an option. I would love to setup a multi disk raid with these to replace my existing 20x 1TB SSD raid. I need both capacity and speed. Any suggestions?
