Sounds nice and all, but my ASRock AB350M Pro4 only has one "Ultra M.2" socket on it. So I'll have to wait for 128GB Optane SSDs, the ones that can actually utilize PCI-E 3.0 x4, not the current crop of x2 drives.
Well yeah, even though it's not super expensive It's definitely a luxury option which people who like the overkill performance can go for.
If you really wanted to you could possibly get a pci-e card with an m.2 slot and make it work on your current board, but you're probably better off waiting for the larger drives anyway.
