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-Grey

I really like and appreciate the included heat sink and heat-conductive padding. In heavy use of the drive, the case now gets fairly warm (about 50 degrees C on a MacBook), but the SSD (not included) works fine at these temps. Well made and nicely sized.

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 )

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

Update 5/2025: Device has now failed sitting in a box doing nothing. I pulled the 512gb ssd out of it to use it for something out, and went to put a old 256gb in for use as a tesla drive, and it won't detect anything. The screw driver, thermal pad, and screws where under the plastic insert - not sure why this was, but the result was a damaged thermal pad. thankfully I had some more, so I used my own. Per the other comments, the thermal design of this is very poor. The heat from the SSD is transferred to the bottom cover, not the top with the ribbing, and there is NO thermal pad between the heat spreader (black metal clip thing) and the case, so it's pretty bad. I added a .125mm thermal tape to help this. The old thermal pad is also a bit thick to allow the heat spreader to clip in - it's a 1mm pad, and with my Samsung 980 EVO 1TB, it's VERY tight on the flash side, so it's not fully clipped around the PCB. Some other people commented about sliding it over, you don't do this. It's a snap-on, and it's tight. there really needs to be another .1mm clearance on it. As long as you're not stressing the drive (IE using it as a boot drive or heavy IO workloads) it should be fine in most use cases, the heat will transfer off. If you're using a fast PCIE Gen4/5 drive, avoid this case, you'll overheat your drive fast.

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.

Speeds are as advertised for a 1TB Samsung 970 Evo (I bought the 10Gbps version), controller seems to do its thing well enough, and the drive is recognized in by Samsung Magician software as a Samsung drive (unlike the equivalent Sabrent enclosure I tried that does not apparently enable this). The problems are with the design of the enclosure. The SSD is installed in a way that results in its chips transferring their heat to the flat underside of the enclosure, which is weird, but since the entire enclosure is aluminum it should still dissipate heat throughout the entire case. Not an ideal design and I've no idea why Orico essentially designed the internals upside down, but it should still do the job. The biggest problem is with the metal sleeve that is supposed to fit over the drive and thermal pad, and then makes contact with the external case for heat transfer: it is designed with grooves for the drive to slide into it, but the thermal pad supplied has adhesive on both sides so once applied you cannot slide anything. I had to bend the outer edges of the metal sleeve so it could just drop on top of the drive and make proper contact with the pad, otherwise it would sit on the drive at an angle so only half the pad made contact with it. The solution would be to either make the sleeve fractionally wider, or provide a thermal pad that's adhesive only on one side. So it works OK overall as a drive enclosure, is physically solid, and looks nice, but the internals for mounting the drive are poorly designed and could be a lot better.

Este dispositivo es genial. aumenté la capacidad de mi macbook pro sin tener que gastar una fortuna en el disco interno. La velocidad es altísima, edito videos desde el disco. Este es el segundo que compro

It worked fine for a while, but there's a small brass fastener of some kind that attaches to the PC board and holds the "back" side of the SSD in place, and that fastener fell off. I could hear something rattling inside. When I opened the case, I found the SSD was floating around, no longer plugged in, and I can't see any way to get the brass fastener back in place. So now this case is basically useless because of this tiny part and flaw in build quality. I will try contacting Orico for a possible solution. Another comment I have is that the case is a lot bigger than it needs to be. Of course the mass of aluminum helps with heat control, but this case has a lot of dead space inside and I have some 4TB SSDs from Kingston and Sabrent with fixed external cases that are way smaller and give exactly the same speed and performance of this much larger case with no issues of heat. So I really regret buying this oversized case because one of my key concerns is portability.

هو جيد جدا وسريع جدا إلا أنه يرتفع الحرارة وغالي السعر اشتريته ب 700﷼ وركبت فيه ssd 990 سريع وحملت عليه نظام الماك Sonoma

good

the case height is greater than most TB/USBC SSD enclosures so there is a large gap between the SSD and the top case. For that reason I guess, they supply an extra metal heatsink that should fit between the thermal pad which they supply also, and the top of the case to transfer the heat to the case. Only it doesn't fit properly on the Samsung 980 SSD. It is too narrow so won’t sit level on the thermal pad. I tried spreading the edges in a vice after which it at least mounted level in contact with the thermal pad. But it didn't look like it was making good contact with the case. So I removed it and added a 1.5mm thermal pad to the one they supply. Luckily I had that. This combination presses snugly to the top case and transfers heat from the SSD to the case. The measured speed (Blackmagic) is fine using an M1 Mac; over 2700mbps on both read and write. But the design of the case is not as good as some other of Orico’s own cases. Those don’t require kludge measures to get the heat to transfer to the aluminum case. Also the case machining is better on those. I would not buy this model again.

The USB C to USB C connection only works when the cable is plugged in a specific orientation at both ends. Even with other 40gbps USB C cables, that is the same case. DO NOT BUY!

First things first, the performance is pretty good. Put a PNY 4TB SSD in and seeing read & write speeds ~2.5GB/s which is about as fast as most TB3/4 drives available. But there's couple of things with the whole package that detract; firstly the included cable is WAY too short to be useful unless you keep the drive basically right next to your computer's usb/TB port. The connector part is also extremely chunky so if you are trying to connect a couple of these in a USB hub/bay where the ports are all side by side it is a tight fit/might not actually fit - I actually had to cut/file down a bit of the plastic around the connectors to fit into my Mac mini. Secondly the 'heatsink' plate is VERY snug, so much so that it actually takes a bit of force to snap the SSD into place with the sticky thermal pad attached, just a tiny bit more would have snapped the SSD I think.
