ORICO 40Gbps NVMe SSD Enclosure, M.2 to USB-C Adapter for NVMe M-Key 4TB SSD 2280, Aluminum M2 External SSD Case, Compatible with Thunderbolt 3/4 USB3.2/3.1/3.0/Type-M234-Silver

Great looking (and working) enclosure
I have a Sabrent Rocket 4 2TB NVMe drive mounted inside this enclosure with the included Thunderbolt 4 certified cable to a Thunderbolt 4/USB 4 port on a MacBook Pro. It achieves 2.5-3.0 GB/ps in benchmarks. I have never seen throttling or heat issues, even when I filled it about 3/4 full initially. It is so much faster than SATA, HDD, and older SSDs that I’ve had that I question if I would ever want something faster. I hope they are still making and selling this the next time I need an external NVMe enclosure.

Great Over Thunderbolt, Issue With USB
I purchased a orico m234c3-u4 and installed a Western Digital 4 TB SN850X NVMe drive. I connected it using Thunderbolt 4 port, initialized it, created a single simple GPT partition and formatted it exFat. It works great and is blazing fast when connected via Thunderbolt, but when I connect via USB-C, it acts like the disk isn’t partitioned. If I try to initialize/partition/format via USB connection, I get an error and the operation fails. I’ve tried via Disk Manager, AOMEI Partition Assistant, and via command line. I sent a message to Orico Tech Support, but never heard back from them. After researching the chips used in the device, I believe that the issue is that the Thunderbolt to NVMe controller that they use will work with 4 TB drives, but the USB to NVMe controller has a maximum drive limit of 2 TB. Since I installed and partitioned a 4TB drive, I’m only able to access / utilize it over Thunderbolt.I’m willing to live with this because I really want the 4TB size and the incredible speed offered by this enclosure, but the inability to use the drive via USB for computers without Thunderbolt is really disappointing. If I could purchase a different enclosure without that problem, I definitely would.On a side note, the top of the included NVMe heat transfer cover doesn’t touch the aluminum enclosure cover when installed. In order to improve heat dissipation, I purchased thermal pads that I placed between the heat transfer cover and the enclosure cover. ( https://www.amazon.com/gp/aw/d/B0BQJGY7H4 )

Faxt! But generates a lot of heat and randomly unmounts on my Mac
I really wanted to like this drive. I used it with a Samsung Pro 990 with heatsink SSD drive and a Mac mini M2 base model with Thunderbolt 4. This SSD drive was too large for the cover plate to fit over the drive, so I used it vertically so that there was a little air circulation. No matter, this drive was incredibly hot to the touch almost all the time. And when I mean hot, I mean fry an egg on top of it hot.Despite the awesome heat generated, this combination was incredibly fast. I don’t have screenshots, but the BlackMagic Disk Speed Test regularly showed read speeds at 3200 MB/s. This was more than I could have hoped for. But it was too good to be true. This drive randomly disconnected multiple times per hour, and each time it would, some application on my computer would hang, and I would have to restart.I switched to a slightly older, slower, smaller capacity WD Blue SSD drive and I thought the speeds would be significantly slower, but lo and behold, the speeds were about 3100 MB/s. Still more than fast enough for my modest needs. I thought that this would be the silver bullet for my random unmounting, and yes, the unmounting has gone down significantly. Maybe be 90%. But it still unmounts, and wrecks havoc on my workflow when it does.I tried another Thunderbolt 4 cable, and the issues remained. At this point, it’s the enclosure for me, and I will be returning it sadly.

Nice looking enclosure with problems
I purchased the Orico M.2 20Gbps enclosure for use with a new Asus laptop with Thunderbolt 4 ports. First problem I had was that the included heatsink did not fit my WD SN770 SSD, causing the SSD to overheat. I cut a 3 mm thick silicon thermal pad to fit between the ssd and the enclosure cover. Overheating problem solved. Next problem was that my laptop would only recognize the Orico enclosure about 50% of the time. Sometimes I get an error message saying that the USB audio device is not recognized. Unplugging and replugging from the Thunderbolt port usually solves this problem after 2 or 3 tries. The best read/write speed I was able to obtain is about 1080 MB/s using the Thunderbolt 4 ports. I tried on another machines having USB 3.2 ports and got around 460 MB/s. Finally, the enclosure sometimes randomly drops offline when used with Thunderbolt ports. USB 3 ports seem to work reliability, but never achieve full speed.

Se calienta muchisimo, no lo recomiendo, seguramente no funciona bien el chip interno

I tried 4 system to get it connected via C TYPE or USB IT it is not showing anything on MacBook pro , Desktop PC and windows laptop and it is not working very bad experience…
