ORICO40Gbps 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-Grey

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.

I purchased this to connect a WD Black SN850 4 TB SSD to a Mac Mini M4, Mac OS Sequoia 15.2. The first unit I received was obviously a customer return, no silicon heat transfer pad in the box. The second unit was factory sealed. Unit is difficult to assemble because the aluminum heatsink fin is grooved to slide over the SSD (not press down on top-too tight). This process is almost impossible because the silicon heat transfer pad which sits between the SSD and the heatsink is sticky and the heatsink cannot be slid over the SSD. I carefully spread the "legs" of the heatsink and snapped in down over the SSD hoping I hadn't damaged the SSD. Well I hadn't but once connected to the Mac, the enclosure cannot maintain a connection longer than a few minutes. I started a file transfer consisting of many folders and files and came back an hour later. The transfer had failed after about 40 GB of data transferred because the enclosure had disconnected and reconnected. While sitting at the computer, I am seeing frequent error messages stating Disk Not Ejected Properly even though I'm not seeing the drive disappear from the desktop. Anyway, this product is poorly designed for assembly and isn't useable for me due to it's inablility to stay mounted.

This enclosure works perfectly. Only thing to note is that it doesn't work with older SSD drives, only nvme.

I use this to extend the Apple Mac mini M4 as there is no internal standard m.2 expansion, still in the latest version of the mini. Thankfully, the standard mini now sports Thunderbolt 4 ports and the 40 Gbps should be not the limitation as the USB ports on the Mac Mini M1.Unlike another external dual SSD drive enclosure I have, the Orico 40 Gbps enclosure only suits one SSD and is fully powered via the Thunderbolt port. That makes it somewhat easier to deal with. In fact, the power brick for mentioned RAID enclosure was relatively massive, and this is a very welcome difference.The enclosure is spacious but also, ever so slightly, not tall enough to accommodate an m.2 SSD with heat-sink. I migrated a Samsung 990 PRO 2TB SSD with Heatsink for PS5 (rated at 7000 MB/s) into this enclosure. This drive was severely hampered by the ports in Satechi expansion base used with an Apple Mac mini M1, and this Orico 40Gbps enclosure is a much better home for it when leaving the lid off. The mentioned original heat sink does not allow to install the lid for it being maybe 1.5 mm too tall. I could remove the pre-installed heat sink from the drive, but the included small heat spreader would be less efficient and, in my case, the enclosure being open is actually hidden under the desk. Still, it would have been perfect if there was about 2 mm more clearance inside the enclosure. (See pictures)The performance with the Mac Mini M4 even somehow exceeded specs with ~3000 Mbps for Read and ~3200 Mbps for Write in the BlackMagic disk speed test. That's enough to enable green checkmarks for all video formats reported by the BlackMagic test. Incidentally, it's also quite a bit FASTER than the built-in SSD, especially in writing (~2000 MB). I opted for the M4 256GB version and now have 2TB of external storage that is faster than the internal. Bonus: Also at a much lower price than Apple could offer an internal storage configuration!Of course, as the MacOS isn't very flexible in supporting different drives from the internal primary drive for software installation, it's mostly limited to data. That's fine for me but might be a limitation to some.

Why did you pick this product vs others?:Ok so I feel for some of the youtube videos. Yes theyre right. Its fast.... for a short burst. Once it heats up, which is within a few minute, it throttles WAY down. I tried almost every thunderbolt NVME housing on amazon and found the OWC 1m2 and the Sabrent (tb3) enclosures to be the best for my needs. The Sabrents a chunky boi. THICK aluminum. The OWC is blazing fast. Id suggest passing on this and go with an S tier company.

The ORICO NVMe SSD enclosure accepts a card-based internal SSD. I measure a read/write speed of nearly 3000 Gb/sec using a MacBook Pro M1 Max with Thunderbolt 4 ports. The case is extruded aluminum, and can be assembled easily with four screws. I installed a Samsung 990 SSD, which generates a lot of heat in operation. The case provides excellent heat dissipation, and includes a thermal transfer pad which fits between the drive and the outer case.

All-n-all this enclosure is one of the best if not the best value for the money - It does work beautifully with a 4TB nmve SSD and does not overheat - My only issue with it is, that using the USB-C one must bend the USB-A rubber strap hard because some ports are seated deeper in the system and the rubber gets in the way. If they made a groove to accommodate the rubber strap to move into that would work flawlessly.

The drive looks to be well made. My issue with it is the drive doesn't touch the case which is all heatsink. It looks like it can cool, but what they provide you doesn't work like that. I added a much thicker thermal pad to get the nvme to touch the case. The cable that comes with the enclosure only lets the in it hit just shot of 1GB/s. I have some spare thunderbolt cables and I tried one and I was able to peak at 2.5GB/s write (image shows slower since I let it run multiple times to test a longer transfer. It's nice that it peaked at 2.8GB/s read. Again, I had to supply my own thermal pad since theirs was too thin and my own thunderbolt cable. I will keep this drive, but I will not buy another from them.
