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.

*edit*
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.

That adapter isn't the one you need... looks nothing like the u.2 plug on your motherboard...

They renamed the SFF-8639 to U.2...you need SFF-8643 to U.2/SFF-8639/SAS.

Have a read: http://www.thessdreview.com/daily-n...r-insight-when-buying-the-intel-750-nvme-ssd/

That's an adaptor in case you only got an M.2 port on your mobo and you want to hook a U.2 drive. In my case the exactly opposite happens. I got a U.2 port and I want to hook a M.2 drive.All I need is the U.2 cable that connects the port on the mobo to the pins on the SSD.
 
That's not an adapter. That is on your motherboard, what I pictured (image isn't from your mobo, but the SFF-8643 connector is). You need that end (SFF-8643) to your motherboard and the other to plug into whatever drive you have. In the case of the Intel 750, its SAS. In the case of OCZ RD400 and Samsung 950 Pro, its M.2 Key M (which I do not think there is a SFF-8643 to M.2?).

Yea I was in a rush and I said that it is an adapter. My bad. What I mean is, I need an adapter than will plug in my mobo's port (SFF-8643) via the wire and will then connect to the adapter that will house the M.2 SSD (say, a Samsung 950 Pro). So we need a U.2 tio M.2 adapter. The one I linked is such an adapter but I don't know if I can trust it or if it's gonna be as fast as a U.2 SSD will be.
 
Yeah... way too complicated... 2 adapters to connect the drive... wow.

I thought you wanted clean and simple (which is simply buying the Intel drive)???!!!

Yea! I was testing the options mostly. So I guess I will be waiting the Intel drive to hit the market or if I'm lucky enough and Samsung has released anything by that time. Thx again! :)
 
i am posting something you might be interested in look for the thread here in a few minutes, in the storage section.
