+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.
