Since I am owning a great new MacBook Pro, I have been searching the web for a worthy external storage to go with it. So far, I only know of stationary Thunderbolt 3 drives (mainly in the form of full-size PCIe boxes with NVMe SSDs in them or large RAID systems that weigh upwards of 5 kg), but I am wondering, whether there's such a thing as an M.2 NVMe SSD enclosure that uses Thunderbolt 3 to connect to the computer. I could not find anything like that up until now, with the closest match being a bulky M.2 enclosure from Sonnet that is called a "Windows Edition" (probably due to an incompatible TB3 chipset, I guess). On the other hand, there are some cheap USB 3.1 Gen1 Type-C enclosures on Amazon, that can house an M.2 SATA SSD, which will not get you the highest transfer speeds possible (in fact, they are pretty limited at the 480 MB/s that USB 3.1 Gen1 supports), with NVMe and Thunderbolt being able to transfer data much faster (theoretically 5 GB/s, but at this point in time the highest rates I could find for desktop drives were about 2400 MB/s). And last but not least there are the Glyph Atom (RAID) SSDs, which get closer (~800 MB/s) to the speed I desire, but still use USB 3.1 Gen2, and they are rather expensive at 1 TB at ~ $ 420. (usual prices for M.2 NVMe SSDs range from 450 to 600 bucks and they are way faster at ~1600 to 3200 MB/s read speed). So my question is: Did I miss something, or are there just no portable Thunderbolt 3 external SSDs/SSD enclosures?
