So far I've only seen USB to M.2 SATAe cases. I don't think you'll see any M.2 NVMe external cases.

Unlike SATA which is a full interface (Phy & dialog) PCIe/NMVe is not (Phy only).

M.2 PCIe/NMVe is a strange beast! Which makes it more complex to implement within an external dumb case. It will require some level of Phy bus driver & micro controller to emulate a PC's PCIe bus. Which could slow the I/O if it's not powerful enough and it would be costly. Look at what a Thunderbolt RAID drive case or PCIe expansion box costs.

I know the difficult of USB to NVME now. But how about thunderbolt to NVME? It is said that thunderbolt is a combo of PCI Express and Display Port.


Here are two examples of cases you could use:

- Thunderbolt2 to PCIe (1 slot): Sonnet - Echo Express SEL ($270 US)

- Thunderbolt3 to PCIe (1 slot): Sonnet - Echo Express SEL ($250 US)

You would still need a PCIe card to hold the M.2 drives as well as the drives them selves (I would limit it to two) and you still would need to make your own OS drivers as Apple does not offer them. I would talk with Sonnet see what they say.

I don't see anyone offering the older USB 3.1 case now that USB-C is available.
