ACASIS 40Gbps M.2 NVMe SSD Enclosure with Aluminum Heat Dissipation & No Noise Design, Tool-Free Installation for M1/M2 Pro/Max, Support 2280 to 2230 SSD Sizes (TBU405 Air)

Fast external Gard Drive
At the price point of $45 this works very well, I added a 2tb SSD NVME and I get speeds in an external drive as fast as my internal drive on my Mac Mini M4. You must use the ; 40GPS port on the computer by a great way to expand your computers memory with out paying Apples insane pricing.
It does get a bit warm while intensive use but works well.

The specs check out – this is a great value.
On my M2 MacBook Air, with a 2TB WD Black NVMe drive installed, I am seeing excellent speeds – close to 2800MB/s on both read %26 write, exactly what I was hoping for. The tool-less install procedure couldn’t be simpler. One thing to be aware of is that they include two thermal pads, a .5mm and a 1 mm. For these to work they need to contact both the SSD’s chips AND the case – that’s how heat gets transferred to the outside. My SSD’s chips barely protruded above the board and it looked like I would need an extra pad to make contact with both surfaces. I stacked both the included thermal pads and things seem to be working great, so I’m relieved. You’ll need software to access the SMART data from the SSD, which reports temperatures (among other things), but even during large transfers my drive stays around 42 celcius – a perfectly safe figure. The case does get warm – which is a good thing, that means it’s doing its job!

This case appears to be one of the (if not THE) most inexpensive TB4/USB4 enclosures on the market. That might be because they claim the controller chipset does not support standard USB 3.2 connections – it has to be connected to a Thunderbolt or USB4 port. If anything happens and you need to get data off an SSD in this enclosure, you won’t be able to connect it to a computer that lacks those ports – regular USB (3.2 or 2) won’t work. I can live with that. Bottom line – so far, this case is delivering, and I’m happy with it.

Best one I’ve used yet
The fan keeps this thing so unbelievably cool. You could probably carry it in your pocket after immediately unplugging it.

documentation slim, seems good value for money
To use in Windows 11, I had to create a volume in “Disk Management.” After that, seems plug-and-play, and seems to me to be good value for money for a disk this speed. I got the non-fan version for $48. It came with a USB cable, plus a thermal pad and what seemed to be adapters for smaller SSD cards; there were no instructions for use of the thermal pad and adapters, but there were simple printed instructions for insertion of the disk, which was easy and tool-less. I’ll buy this enclosure again if I need another external SSD.

The item was list as having an 8TB NVMe drive installed in the docking station and for the price looked like an exceptional value. When it arrived there was no drive. My attempt to contact the seller was worthless as they didn’t understand basic English and the responses made no sense. I returned the product and got my money back.
