"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?** A: 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?** A: 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?** A: Yes, I have the 1TB Samsung 980 Pro running in my Acasis case with no problems on either MacBook Pro or Mac Mini Pro. ## Frequently Bought Together - ACASIS 40Gbps M.2 NVMe SSD Enclosure, TBU405 for M1 M2 Pro/Max, Compatible with Thunderbolt 4/3/USB3.2/3.1/3.0/2.0, M.2 Enclosure Support SSD 2280/2260/2242/2230 B+M M-Key - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
