Is there an easy way to adapt nvme m.2 to sata

[mallenwho]

I've currently got an ATX z97 motherboard with an nvme C drive, installed in a riser card in a PCIe slot - Because of course the z97 chipset was before m.2 slots on motherboards were a thing.

 

I need to migrate my computer into a tiny case so I have an itx z97 motherboard. It also lacks an m.2 slot. It only has the one PCIe slot and I'd like a graphics card. 

 

 

 

I've found devices such as these https://www.ebay.com.au/i/112562167122?chn=ps which are basically a sata header to m.2 adapter, in a 2.5" enclosure. To me, that means they're using the sata m.2 protocol, not nvme. Is there a straightforward way to have an nvme drive run on a sata interface? Or failing that, to split a 16x PCIE lane between a 4x and 8x slot (or 2 8x slots) so I can have the adapter card too, all while being flexible ribbons because it has to fit in an itx enclosure.

 

Thanks for any help or wisdom.

Nvme can be adapted to pcie, or usb 3.1 gen2, but nothing else that I've seen. It needs pcie lanes to function.

Why would you buy an nvme m.2 and then bottleneck it with sata protocol speeds?

Could have been purchased by accident.

You could sell it and get a 2.5" SSD and secure it inside the case with 3M double sided tape. You won't get the full speed of your current m.2 SSD, I would sell it and get a larger 2.5".

I've been happily using the nvme at speed for a year, but I now have a need to migrate the system to an itx case and there's not enough PCI slots to go around (for the adapter) it's not ideal but I'd much rather adapt the drive than copy the contents to sata.

In that case, sounds like the best call is some sort of pcie ribbon splitter...
