Hi all!

I have Asus Maximus VIII Impact mobo with U.2 port. I would like to use Samsung 960 M.2 storage with it. I've found this: "U.2 (SFF-8639) to M.2 (NVMe) SSD Adapter".

Would using that adapter degrade the speed of the storage?

Thanks!

I can't use PCIe because it's a mini ITX mobo and the only port is occupied by GPU.

I thought that connecting that adapter should be possible using a cable like that:

(Funtin U.2 (SFF-8639) to HD Mini-SAS (SFF-8643) Cable for 2.5" NVMe SSD)

I was limited in available options :(

Actually, it does have an M.2 port, but it's occupied by preinstalled wifi/bluetooth module. And I want to keep it as well.



Yeah, theoretically that should work. But would that degrade the performance?
I wouldn't want to buy expensive Samsung 960 and not to use at least ~95% of it's speed.
 
there is supposed to be very little (if any at all) performance degradation (both are PCIe x4).
Anyway, except few rare scenarios, you are not going to feel advantage of the extremely fast NVMe drives over good SATA drives.
I have a macbook pro with quite fast NVMe disk and can't say I "feel" the difference over the M.2 SATA drive in my desktop.
I can definitely "see" it if I run synthetic benchmarks.

I'm just curious - where is that M.2 for wi-fi is located on your board. I couldn't find it on images. On my mini-ITX board it's compatible with very short modules and i'm not sure it even supports storage devices.

It should be where the "Wi-Fi Go!" module is installed. At least in the manual it's marked as M.2(Wi-Fi).
