I have a Crucial NVME ssd https://www.crucial.com/ssd/p1/ct500p1ssd8/CT13114837 and an Asrock mobo https://www.asrock.com/mb/AMD/B450M Pro4/ . The Board has two NVMe slots, one listed as Ultra and the other not... This is the first time I've worked with one of these and I'm unsure which slot this is supposed to go in? I think it's the Ultra, but am not certain?
