USB4/TB4 with m4-pro macbook pro. Also working with AMD x670e chipset w/intel-maple-ridge TB4 chipset w/linux kernel 6.11.x. Full USB4/TB4 speeds on both platforms.Would recommend.Only con would be the short cable (especially when connecting to a tower IO panel). Have yet to try USB4 extensions

Nice enclosure. Excellent build. Memory stick fits perfectly blazing fast. One issue is the cable is a bit short for my needs, nothing that an extension cable won’t fix. I highly

I’m really enjoying my NVme SSD enclosures. Now that this memory has declined in price over the past few years, they are much more affordable than just a few years ago. The enclosures too, there were hardly any even a year back, but now have exploded into the market and this segment is continuing to rapidly expand. In my opinion, it’s a great idea, as even in their day, I couldn’t stand the spinning discs.Having taken a bit of a look at these enclosures, I initially thought they were all the same. But wow, there are nuances with this type of product too. What speed they perform at, what chip(s) they utilize, size, heat dissipation. Initial models I purchased had some awful heat issues. The manufacturers seem to still be addressing this point. I have in general found, the larger units do the heat management better. Whether they have a fan or not. And then some SSD sticks use slightly greater voltage handling large file loads. Some sticks have high idle voltage. If things aren’t quite simpatico, disconnect issues happen, some users report just general shut downs. So it’s worth paying attention to stuff like this when choosing the right stuff. Though, I’ve found almost every SSD brand in the 2280 size has really good reviews. I can only imagine the high end precision these Asian factories use when making them. Too bad Canada and the United States can’t make these for the same cost.The Cable Matters is a relatively new entry into this segment. So what stands out here? A fairly large housing that opens like a book. The chassis is typical, mostly aluminum with plastic parts inside. The design is actually very good because it’s easy to access the memory and easy to change it out, if needed. Especially if you have sausage fingers. A stand out feature, you need not have to remember to bring the correct cable with you. It comes with a permanently attached unmarked Thunderbolt 4 USB C cable, which, cleverly gets tucked inside the housing when not in use. I found the length, which is maybe 8 inches or so, long enough to use with my MacBook Pro without issue. I have felt each time I’ve finished using it though, I want to let the whole thing cool down before reinserting the cable. I mean, this case doesn’t get super hot like some others, but my idiosyncratic side feels I should put the cable back when most of the heat is gone. If you’re like me, then this can be an extra step in the equation of packing up. I usually wait about 10 minutes or so before putting the cable back inside the housing. In that time I normally tidy the rest of my stuff up as I’m usually done for the day. You might get what I mean. A separate usb C cable on other cases would just unplug saving you this small trouble. If it’s considered as an issue at all. But, one bad tug on the attached cable, this case can be toast, as there’s no other way to use the case But if you are careful with your stuff, chances are, only a bad accident can ruin the Cable Matters enclosure.The housing feels relatively well made, but can’t say super premium. Construction/engineering is good. The chassis has a small led that shines in blue for 40GBS file transfers and green for slower speed use. The latch works. It’s a latch. Not particularly smooth in operation though.I included some speed tests. Please know I am not a professional or expert, just a hobbyist. Equipment utilized in all my tests;- [ ] Cable Matters 40 GBS enclosure with supplied TB4 attached cable- [ ] Samsung 990 Pro SSD 2 GB- [ ] MacBook Pro16 inch M2 (purchased new in 2024).Amorphous Disk Mark provided decent speeds using a 32 GB load over a single test. My understanding is a larger load stresses the memory to a greater extent giving us a better real world use in numbers. In addition, I used the traditional Blackmagic measuring app. Again, numbers are respectable.I have other enclosures, made by Ugreen and Acasis. Using the exact same equipment the numbers were very close. Any differences were not noticeable unless I used a stopwatch when transferring even large files 50-100GB.Where I found a difference was in my Ugreen (model 1576), the heat under even light load is ridiculous. I can’t recommend using it in the combo above. The Acasis TBU405 is the coolest case I have used in the above combo and speed has not suffered. The Cable Matters is a close second to the Acasis TBU405. The Acasis and Cable Matters look and feel like they use the exact same aluminum materials for construction.If I had to buy again, I highly recommend either the Cable Matters enclosures. I use the Cable Matters with the Samsung 990 Pro for Time Machine backups. Having previously used a Samsung T7, my gosh the difference is welcomed. On my last Time Machine backups with the T7, it took well over 2 hours (about 450 GB). With the Cable Matters enclosure and Samsung 990 Pro, maybe 15 min or so. This will only be appreciated even more in future backups as they will be slightly larger as we get on. As to the rest of my unscientific tests, I do allot of video editing using Final Cut Pro and Wondershare Filmora. The Cable Matters and 990 Pro were brilliant.I’ve personally bought several pieces of equipment from Cable Matters over the years. Their quality and reliability are both great. They don’t lie about the speed of their usb cables, which is an important feature when they publish their adverts. Their overall quality is also very good with everything I have from them. So I would recommend this case to everyone.

I have used different NVME enclosures; this is the best of them all.Its ease of installation and internal cooling design makes it a must buy device.On my Mac mini M4, the read and write speed is approximately 3800MB/sSurely, I will recommend this product to all.

Very nice enclosure. Design is particularly unique among the many I have owned.There's a slide button to unlock it, then it opens like a book revealing the SSD compartment and the integrated USB-C cable. Comes with thermal pads attached for the top and bottom. Supports 4 sizes of SSD with a rubber pin that can be moved to any of the 4 peg holes. The USB cable wraps around a channel inside to be stored neatly under the cover when not in use.My one criticism is the cable storage sharing the compartment with the exposed SSD. Especially since to fish the head of the cable out you have to jam your finger right up against the SSD. Call me paranoid but I'm constantly afraid of ESD frying my drive in this situation. Otherwise, it's a pricey but wonderful enclosure.

Super happy with this so far. I'm using a Crucial T700. Only issue was that the bottom thermal putty was too high for the end of the drive to latch. So I had to take a usb adapter and use it as a roller to gentle flatten the putty down until the end could latch. Most drives don't have chips on the bottom like the T700, so this won't be an issue with most drives. With the clam shell latched the top putty didn't contact the drive, but I had some thermal pads leftover from other enclosures. Write speed was 400MB/s faster than my internal Mac Mini M4, read speed was about the same. The fan is completely silent. I just wish there was some kind of fan control app. I'd like to keep the base rpm high to keep the drive cooler at idle since the T700 pulls 3w at idle. I did some power draw testing using iStat since there's no info on that from Cable Matters. Mac Mini idle = ~6w. Mac Mini idle with idle CM enclosure over USB 4 = ~12w. Mac Mini with CM enclosure over USB 4 with 800mbps transfer = ~26w. Mac Mini with CM enclosure over USB 4 with 2,600mbps transfer = ~26.8w.So the Cable Matters pulls ~6w at idle, and ~20w for large GB transfers. This could be because of the T700 drive I'm using. The T700 uses ~3 watts at idle and up to 12w peak. This implies ~8w max for the enclosure itself with no drive. Most regular drives pull 5-8w max, so make sure your usb-c port supplies at least 12w. I was having overheating and disconnect issues with the T700 in other enclosures that underpowered the drive and didn't have active cooling. But so far the cable Matters enclosure seems to be supplying enough power and cooling to keep the T700 happy. Customer support said the enclosure can deliver up to 15W to a drive and that it is designed to handle high performance drives like the T700. The bottom of the enclosure always stays warmer than the top. This is mainly due to the enclosures controller chip. Being made in Thailand is also a plus. The latch and metal case feel like they'll last forever. The center black part that the drive and controller are attached to is plastic. But it also feels very durable. I was originally looking at a waterproof enclosure, but they just can't vent the heat fast enough. This enclosure with a Pelican 1020 for transport is a great alternative.

I think I'm done looking, ASM2464PD enclosures have been around for a bit but none of them seemed to hit all the details right until now.Almost every design out there considers the heat from the SSD but most ignore the Asmedia USB4 controller which by itself uses a fair bit of power in a tiny space. You can read other product reviews with nice pretty benchmarks but so many user complaints out there about throttling & disconnects for sustained use.I took this apart first thing (4 tiny screws under the cable dongle channel, no glue or stickers) and you can see the controller has a thermal pad that mates with the bottom heatsink right next to the main airway.The clamshell side is easy to use, I'm really sick of all the ones with sometimes multiple layers of tiny screws just to change drives. If a drive has anything thicker than a basic sticker (looking at you FX900 pro) or has a permanent heatsink you can leave the door open and it still works.They did go with an embedded dongle cable which is a plus or minus depending on your POV. You can't lose it and it nests completely inside the clamshell for storage. But its also fairly short & using a soldered daughterboard, so if it gets damaged then replacement would not be simple. I get why they did it this way for a portable unit, saves them dealing with user's random cables that are not up to spec.In actual use it works great, not too hot to touch nor does the fan sound annoying for complete drive clones or transfers (I think its actually off when idle/cool). I can confirm on USB4 ports it is true native PCIe that allows full access to the drive with all software tools, I used it to firmware flash a stack of 980 pros that were long overdue. (samsung updater tries to force a reboot but you can process kill it when completely done)I would note that if using in USB4/PCIe native mode (blue light) you might need to make sure the port has at least 15W PD, the lowest spec of 7.5W might be borderline for combined power when using this with top end PCIe 4.0 drives. USB3/UASP mode (green light) should be fine with almost anything.If you're basically never going to change the drive and don't mind a larger case I would maybe consider the 1M2 "DIY" version since there is no little fan to worry about clogging up with dust, but if you are doing more admin/technician/hobbyist work with drives this is the winner.If you are swapping TONS of drives (like several every day) keep in mind any m.2 connector itself does have a finite limit on insertions. Its probably hundreds depending on gold plating thickness, but at that point its fair to say you can justify buying another.
