both still use pcie lanes, the difference is the connector. i am probably wrong but i think u.2 is more for server setups since the drives could be larger in a way then normal consumer drives.
*edit*
so im not sure why you cant trust adapaters, i have used IDE to SATA adapaters they worked fine. nearly ever external HD enclosure uses an adapater to take the drive from SATA to USB/FW.

when you got some of the top motherboard manufactures making the adapters, its safe to say they work.

not sure how i found this but if you look closely at the connector on this adapter

this is a sas connector, the u.2 connector sure does look like a sas connector.
Hey Evilsizer, I found an adapter U.2 to M.2 (the one you posted is M.2 to U.2) that is from an unknown maker, that's why I said I can't trust it blindfolded. The only solution is to either wait until U.2 SSDs start getting produced or get a regular SATA drive.

This is the adaptor I was talking about.
