Any recommendations for >20gbit/s enclosures with passive cooling (that are also not huge)?

I have a 10gbit/s enclosure and a 4TB gen4 nvme in it. It pains me to know that it could achieve >3GB/s write speeds but hindered by the interface.

Highly recommend this site: https://dancharblog.wordpress.com/2024/01/01/list-of-ssd-enc...

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.

+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.
