I have three Acasis TBU405's two running Samsung 970 EVO’s and 3rd runs a Silicon Power NVME for more than a year now. They have been rock solid. Same speeds you see. Prices have dropped by almost half on these cases from when I purchased them. Mine run at 50°C when in rest and a little warmer under load. No regrets.
hmm.. what about access latency compared to built-in drivers? TB4+ seems to remove the drawbacks of having external drivers, my only concern remaining is random access latency.
the 990 basically eliminates the bottleneck, also pretty much all the enclosures top out close to 2700 in real world speed tests, TB4 can support faster, but its a device issue typically.

Problem is when it’s connected to a Mac it stays hot even when Mac is idle. Seems to be Mac’s continue to give a lot of energy into it even when idle.

What does the switch do? Also should I eject it at night before I goto sleep?
Thanks for doing the review!
No problem, glad you liked it!
Thanks for this great review!
Glad you found it helpful!
what does the switch button on it do?
I would like to know also can’t find answer anywhere.
it's for the TBU405Pro model which has fan, to turn it on or off
990 pro is overkill for thunderbolt 4 and 2700mb/s is not the ideal speed of thunderbolt 4
990 pro is providing better random small block read speeds even on TB4
