JEYI M.2 Enclosure, USB 3.2 Gen 2 10Gbps M.2 NVMe SSD Enclosure NVME PCI-E M-Key External SSD Enclosure Support UASP Trim

This thing is awesome. The only thing I would improve on is possibly better cooling, 'cause it runs really hot, which might trigger thermal throttling of performance. But that's to be expected with such a small enclosure. I honestly don't know how better cooling would be accomplished without sacrificing the compact size of this unit. I'd rather keep the throttle to stay at this size. It only gets super hot when doing larger data read/write operations. I have installed whole OS (Windows 11) booting on a Steam Deck and it runs great. Runs just as fast as the built-in SSD.

So far, I haven't had any problems with this enclosure. I've been testing it with a Seagate Firecuda 2TB NVMe SSD (2230) and, in most usage (transfers under 40GB), it doesn't get very hot. My use case is Carbon Copy Cloner to copy a 1TB Mac system disk. After an initial copy of 310GB, most copies are now around 5GB, with occasional copies around 30GB. 5GB clones usually complete in under 30 seconds (about 170MBps). In a pure speed test with Blackmagic Disk Speed Test, I get 900MBps write and 860MBps read. These are pretty respectable numbers, considering that the USB-C interface on this enclosure is spec'ed to run at 10Gbps (about 1000MBps).If you're doing a very large operation (copying a 200GB file, for example) the enclosure and the SSD will get very hot. It's imperative to use the included heat-transfer pads. In one very large operation (over 300GB) it was getting too hot (in my estimation). So at first I was pausing the operation every 10GB to let it cool a bit, but eventually wrapped it in a layer of moist paper towel sitting on an ice pack. It stayed cooler than room temp and completed the operation in record time without problems. I won't have a need to do anything like that for a long time, so I'm quite pleased with this enclosure for the moment.If I could improve anything, it would be to make it even smaller: Does it need the key ring opening for cooling? Could the 27.9mm dimension be made smaller? Otherwise, it's a solid, well-made enclosure. I'll update this review if I encounter any problems. The only other very small enclosures I've tried run at similar speed, but are a tiny bit larger in the long dimension (but a bit slimmer and narrower).

Was looking for an enclosure for my Steam Deck SSD after replacing mine with a 1TB SSD. Chose this product for it’s size, the fact that it was designed exclusively for a 2230 SSD, the inclusion of a screwdriver for this device, and due to having seen another review of someone using this enclosure specifically for a Steam Deck SSD. This kit includes everything one would need to install your SSD and more. The extra inclusion of a strap for the enclosure, plenty of extra thermal pads, both a USB-C to USB-A (3.0) cable and a USB-C to USB-C cable, and an extra screw in case of stripping or losing the original one was greatly appreciated. This kit is a great value for the money in my opinion.My computer had zero issues recognizing this device. Once plugged in, I went into disk management and deleted all the extra partitions that were created on my SSD for the Steam Deck, added a new partition, and formatted the drive. After this, I was able to easily and quickly transfer my files from my PC to my SSD.My only minor criticism is that the included instructions were exclusively written in Chinese. Although this was a bit disappointing, I was easily able to use my phone’s translator camera feature to translate and review the instructions.Overall, I am very happy with my purchase and would recommend this enclosure for anyone looking for an enclosure for their Steam Deck’s SSD or simply for anyone in need of a 2230 SSD enclosure.

TL;DR: This is a good enclosure but gets really hot and if you're moving a lot of data all the time rather than more typical uses, it might not be the best choice.Pros:- Compact and well built, feels solid- Easy to assemble- Includes thermal pads- Comes with the ubiquitous cheap Chinese screwdriverCons:- Does not come with instructions, but it's also pretty simple.- Gets quite hot. I got this to back up SD cards with my laptop and under sustained loads of only around 30 MB/sec, the enclosure reached 133 F (56 C). This isn't hot enough to be dangerous to the equipment and there's still headroom, but be wary touching it after sustained data transfers. If you're pushing higher speeds for longer, it might be a bigger problem.I paired this with a 512 GB Sabrent NVMe drive.

This item is perfect for carrying a high capacity NVMe in one's pocket. I have just purchased and set up my second one to upgrade my NVM storage to 2 terabytes. My first one, purchased a year ago, has held up perfectly and reliably provided High speed access to a 1 terabyte NVMe. I am completely satisfied with this case and recommend it to anyone needing a small form factor case for an NVMe up to 2 TB.

Device is a nice size for a 2230 SSD. Unfortunately, the chipset keeps dropping off of my systems after a short period of read/writes. It's fine for a short period, but after about 5 minutes to write, the drive stops responding. I know it is the device enclosure chipset, as I have had zero issues from the SSD while in other enclosures.Also noticed: even though USB-C is supposed to be reversible, this device only seems to work one way. If reversed within the socket, it fails to read. I have a feeling that it's the internal USB-C connections only being on one side of the connector in order to save money. I'm unsure, as this is the only device enclosure from this company that I own.I would consider some other brand, if possible. I will not be buying again. If the manufacturer could step up with their support, that may be helpful. I hope that I only have a defective unit.
