(with "E") the box states the included cable is Thunderbolt 3. it drops the false claim printed on the earlier TBU401 box of "USB 4.0". -----( newer TBU401E )----- https://m.media-amazon.com/images/I/41n8r+Qr+4L.jpg https://m.media-amazon.com/images/I/41vqV5YTrjL.jpg https://m.media-amazon.com/images/I/61iyaANm7qL.jpg https://m.media-amazon.com/images/I/61TKeFrG5NL.jpg -----( original TBU401 )----- https://m.media-amazon.com/images/I/81-0pILAsAL.jpg it seems like all brand enclosures boasting "40Gbps Thunderbolt4 / USB4" are JHL7440 chipset based. the JHL7440 is actually Thunderbolt3, (not TB4 or USB4), which actually produces only 22Gbps data transfer. (per Intel, 18Gbps of 40Gbps is reserved for Displayport video). they also do not support USB Gen 2x2 20Gbps mandatory with USB4. only USB 3.1 10Gbps. there's no telling which exact model ACASIS (or anybody else) is shipping at this very moment. none can possibly transfer 40Gbps - that's 5000 MB/s. they all get approx half that. none are USB4 - their USB interface is only USB 3.1. that's all there is to it. the ads are all consistently deceptive and untruthful. and most Answerers in the Q&A only help compound the fraud. . **Q: Does this enclosure support nvme 4.0 or only 3.0? will using a 4.0 capable drive provide speed improvements with this enclosure?** A: No, you most likely will see no difference as others answered partially but not directly. You are bottlenecked by 1- Thunderbolt 3, which theoretically can handle 40Gbs/5,000MBps, but in the real world in my experience tops at 3,500~ish. 2- Various other parameters such as cable quality, NVME drive technologies, SLC, TLC, QLC, VNAND, etc. My suggestion: Buy the BEST NVME 3.0 you can, with the largest DRAM or SLC cache, AND make sure that below that cache it has VNAND instead of regular NAND. Keep an eye on too high densities as well. SLC is faster than TLC which is faster than QLC… Best. R. **Q: Hi, does this drive run a 10gb if i hook it up to a regular usb 3.2 gen 2 port? thanks!** A: USB 3.2 Gen 2 max speed is 10 Gbps. The USB port cannot get faster speed, just because a faster devices was connected to that port. **Q: What is the difference between tbu401 and tbu401e?** A: review photos show the models are marked differently on their aluminum bodies.
