Did they every actually make any SATA Express drives?

I'm in the process of my mini itx build and I'm already using the PCIe 3 4x M.2 for my primary storage. I'm looking to possibly add a second drive for more storage and I figured since my motherboard has SATA Express (Do they just call it SATAE??) I figure I will try to squeeze as much speed as I can. However doing a quick search on newegg and google, I don't actually see any production drives? Is this true? If so, why are so many motherboards still trying to push this tech when their aren't even any products to use it?

Thanks!

Only retail drive I've seen, outside of high end enterprise stuff, is the Intel 750 U.2 drive.

But you can also get a U.2 -> M.2 adapter, which lets you add any M.2 drive you want. Probably the easiest way to go, since U.2 is pretty much dead
M.2 to U.2 SFF-8639 PCIe X4 GEN 3 Adapter # SFF-937-4XGEN3

There are probably others out there, but that's the first I found.

U.2 is different than sata express

Ha, that's right, got my backwards compatibility mixed up, you can connect SATA Express drives to a U.2 connector, but not the other way around, since SATA Express is 2x PCIe and the newer U.2 is 4x PCIe.

You can just plug 2 regular SATA drives into a SATA Express slots. So if you are just looking for more storage and don't need absolute top speed, that's the way to go.

SATA Express would have been amazing 7 years ago.....
