I started off with the Acasis Thunderbolt 4 enclosure. I can confirm that the Acasis unit does indeed have a Thunderbolt 4 compatible board, and the UGreen does not. However, my testing didn't show a huge difference in speeds, at least not enough to justify the trade off in thermals. The Acasis unit got VERY hot. The included thermal pad is not thick enough to reach the top aluminum plate, and I assume they do this as the Acasis seems to be geared more towards swapping NVME's regularly, vs the UGreen which seems to be geared toward installing once, and that NVME living in the enclosure long term (tools vs tool-less). The operational temp for most NVME SSD's is technically 30*C-72*C (86*F-161*F). In the Acasis, even at idle, I would clock the enclosure up at 120*F, and the drive with the top plate removed at 123*F. Under a blackmagic stress test, I could easily get the drive up to 155*F and enclosure up to 162*F. While that is within the margin of safety, and the enclosure is obviously dissipating heat as it was hotter than the drive itself, that was just too close to max temps for my comfort and I really think long term that the drive would not live very long. Now on to the UGreen. The design is MUCH better. The fan does do something. It doesn't pass air over the SSD itself, it moves air from under the SSD and over the enclosures main board. The big difference is the UGreen has a solid copper to plate, and the included thermal pad is thick enough that on a standard NVME drive it brings the height up to the height of the rest of the enclosure (you can see it in photo 2) and the NVME makes DIRECT contact with the copper plate. The temperature readings I took were after running blackmagic 5GB stress test for 10 minutes straight. The second photo at 92.3F is of the lower end of the NVME, the 108*F is the upper end. The memory modules themselves were in the 92-95*F area, well within my comfort zone. Overall, I'm much more happy with this unit over the Acasis. I think the Acasis could work if you went and got a thicker thermal pad, but I love the aesthetics of the UGreen, and in my use case, this is a drive that will always live in the enclosure, so having a screw to keep it installed is actually a pro for me. I skipped the included rubber wrap as NVME's aren't going to be damaged by shock or vibration, and I don't care if the enclosure anodizing gets scratched. Blackmagic test results done on a Macbook with thunderbolt 4 capabilities, although it is falling back to USB 3.4 due to the controller in the UGreen not supporting Thunderbolt 4. Still plenty fast for me, and way faster than any off the shelf external SSD offering. Read more

It's not working and sadly I miss my windows to return it I try everything just didn't work feel like this not even ssd since you can feel the disk is moving inside Bad product that why it's so cheap for 4TB Read more

i bought this enclosure i was happy with the speed the problem is this enclosure disconnect after 20 min of using and u need to reopen it remove ssd and put it back , and after that he keeps disconnecting bad encloser dont buy it Read more

Well built and reasonably compact considering that it has a fan inside. The rubber jacket is a nice and protective addition. It did not include a Thunderbolt 4 cable in the package which means you can't get the full performance right out of the box. Although I was able to achieve well over 4000 MB/s read and write on Blackmagic Disk speed 1 GB test with a Samsung 2TB 990 Pro, the connection to the MAC regularly dropped under sustained load, resulting in a "disk ejected" message. It wasn't reliable enough for large file transfers and video rendering. Unfortunately I ended up returning it and settling on slower but more reliable Thunderbolt 4 enclosure. I would have loved to keep it if it was more reliable. It is possible that this is a specific defect with this particular unit. Read more

with Heaviness, but it’s Fine, it stays on my desk, for TIME MACHINE. SOLIDly-Built, SO Fast!! Heats-Up, and Well—compensated by its FAN. ☺️🙏🏻🙏🏻 - Terrence Hil Photography International Read more

Samsung Magician software won't see if the drive inside if it's a Samsung drive. Fast, beautifully built, well cooled, but keep in mind if Thunderbolt protocol is something you explicitly need. If you were planning to update the firmware in a 990 Pro, you might need to put it in the machine directly before putting it in this enclosure. Read more
