PCIe 4.0 M.2 SSDs have been pretty slow in appearing. It's like everybody's concentrating on PCIe 3.0 still, with an occasional PCIe 4.0 drive as an afterthought. I currently have a single PCIe 3.0 M.2 drive. I have another M.2 socket unused, but I wouldn't want to spend it on another old PCIe 3.0 drive.

NVMe market is starting to become like SATA SSD market a few years ago... ... a big MEH. Barely any differences from product to product, they all cost pretty much the same, capacity also isn't increasing that much anymore. (They are getting a bit cheaper though, so that's good I guess for those who are still on SATA SSD, or worse, still using a HDD)

Being that only AMD supports PCIe Gen 4, there is a limited market for such drives right now.

They push to reach the limits of the interface as fast as possible.... At least with SATA SSDs, it took a little while to reach full bandwidth. I'd bet most of the NVMe SSDs are just rebrands anyway....

No power or sata cable required is nice bonus though.

ur post is vague, but i see the root of the problem, and may point u in the right direction, if not to a solution if ur using ur 16 lane asus m.2 x4 adapter in an 8 lane slot, it can only run 2 x4 m.2 ports as u would expect, but even then, that 8 lane slot needs to be "bifurcated" in the mobo bios. (split into a 2x x4 slot vs default 1x x8 slot) not all mobos do this. in the default mode ur using, ur expensive m.2 adapter is only showing 1 m.2 port as i would expect. u could get the same result from a x4 m.2 adapter costing a few dollars.

ty for your reply i try putting 2 of the ssd in the motherboard and they show up in bios and then try to get second 2 to work in the asus 16x but only one would still only work so i decide to buy another adapher that uses 2 ssd and have 2 in motherboard it arrive tomorrow
