+1 for that Acasis. I've had one for 18 months and use it for occasional >1TB backups and big transfers to/from a Dell XPS laptop running Winx64. I benchmarked it with DiskMark64 and speeds are as expected for 40Gbps-class xfer.
It was much cheaper to order the laptop with the smallest stock Dell NVME (512GB generic) and immediately upgrade it myself to a 4TB Samsung 990 Pro. The external enclosure made the upgrade much quicker and the savings more than paid for the enclosure plus I got a faster 4TB NVMe than the generic stock Dell NVME 4TB for less money.
It's key to get an enclosure with a chipset that will support whatever interface your computer actually provides, otherwise a lot of these enclosures will fall back to USB-3 speeds for compatibility and things will be slow. This site gives a pretty good overview of the chipsets out there and pros/cons of each one.
I've had good experiences with Acasis[1] enclosures - they seem have a lot of aluminum surface area for dissipating heat - but I get the feeling that a lot of these things are very similar in practice since they're just slapping the same chipsets into different boxes.
