Q: Is this the newest model or is there a newer model out?

who can tell what's truthful, with all this bogus 40Gbps USB4 marketing documentation. the ACASIS site presently states this TBU405 contains "Intel® JHL7440 Thunderbolt™3 with REALTEK® RTL9210B" that USB interface chip RTL9210B is USB 3.1 • 10Gbps. but the Q&A here states it's a different chip JMS583 with that same lowly USB 3.1 • 10Gbps. the ACASIS tool-less model TBU401 is now shipping with TBU401e on the box. "e". but that Amazon sales page and the ACASIS online marketing page don't mention anything about that "e" model update. it's also documented to contain a RTL9210B chip. but a video shows it formerly contained a JMS583. https://www.amazon.com/ask/questions/Tx220PG5HNIY0I3 so. what you see here might NOT be what you get. .

Q: Looking for those who have tried a wd sn850x gen4 in this tbu-405 enclosure. all work well? any performance drop / fails? does it handle gen4 well?

based on below details • there is adequate power supplied by TB. • but insufficient power from native USB. google online image of this WD SN850X sticker shows 3.3V x 2.8A = 9.24 watts. M.2 specification 1.0 states its max power limit is 8.25 watts. that's a little puzzling isn't it? this enclosure's Intel JHL7440 Thunderbolt3 chip datasheet average TDP power is stated to be 2.4W exactly how much more power this enclosure requires isn't disclosed. 9.24 + 2.4 = 11.64 watts native USB4 per published specification can supply only 7.5W (for x2 lane, only 4.5W for USB x1 lane) Thunderbolt3/4 specs are not publicly available, but unqualified online claims say 15W ------------------------------------ regarding speed of this Gen4 7300 MB/s SSD it can get only approx 2750 MB/s in this Gen3 enclosure. if you're happy with that substandard performance from Gen4, very good but it's not even Gen3 top speed.

Q: What is the difference between acasis tbu401 & tbu405?

according to the Seller in that ad, the two models have the exact same chipset. so the functional difference would seemingly be only that the 401 is tool-less. https://www.amazon.com/ask/questions/Tx220PG5HNIY0I3

Q: Compatible with Samsung 980 or 990 Pro?

Yes, I have the 1TB Samsung 980 Pro running in my Acasis case with no problems on either MacBook Pro or Mac Mini Pro.
