Hello, I don't know the product & am waiting for delivery. How exactly is this to be understood with the M.2 memory? 1a) Do you need a holder, a "fuse" or something similar? 1b) Do you have to buy something extra for it or is there an item no. here at galaxus.ch? 2) Which memory types are possible (e.g. length, speed, not only capacity,...)? 3) Does anyone already have experience with this product and the M.2 memory? 4) Does anyone have an M.2 purchase recommendation for this or will there be any suitable accessories to follow? Such an M.2 or USB solution (e.g. with a large capacity) is actually advantageous in order not to have to keep a NAS running all the time. I think this Cloud Gateway offer is strong from Ubiquiti, although the network connections were not the reason for the purchase per se.
