ACASIS 40Gbps M.2 NVMe SSD Enclosure, Only Compatible with USB4,TBU405 Air for M1 M2 Pro/Max, Tool Free Installation, Support M-Key Interface B+M 2280/2260/2242/2230 SSD Size

Easy install and plug and play product ,with samsung 980 NVMe M2 i was able to achieve 2754 MB/s Read & 2802 MB/s write speed perfect for 4k video editing directly from external ssd instead of copying to my local. Best product and very much satisfied.

I am blown away by the speeds that this SSD enclosure can deliver. I've got mine paired with a Samsung 990 PRO 4TB SSD and plugged into the Thunderbolt port of my Mac Studio. I'm seeing read/write speeds in the 2700 MB/s and 2600 MB/s range, which is so much faster than my previous 10 Gbps enclosure (which was achieving roughly 600-700 MB/s speeds). And this is with the SSD about 45% full. I use my system for video editing 4K content, and the scrubbing speed on my timeline has become instantaneous. I can quickly scrub through the timeline or jump to different parts of the video with ease... no lag anymore! Installation was super easy... just open the fully aluminum case, insert the SSD and rubber mounting plug, then push the SSD into the enclosure (no screws or screwdrivers needed). Close the cover and you're done. My Mac recognized the drive immediately. The enclosure can get warm (to slightly hot) when I'm rendering a long duration video, but that's expected of any SSD or hard drive. To keep the enclosure (and SSD) cooler, I keep the enclosure on top of my Mac Studio (which has an aluminum shell)..... this helps to dissipate heat a little better than if I were to place it on my wood desk surface. The enclosure looks great; it's sleek and minimalistic with cleanly milled heat-sink grooves. And the all-aluminum design is very-nicely machined and matches the design language of my Mac, awesome! I don't have a PC, but this is fully compatible on my Mac Studio running the latest MacOS.

Very nice case, but get a fast enough SSD unit for it. I originally had a "Crucial P3 PCIe Gen3 NVMe 1TB SSD, Up to 3,500MB" SSD in there, & that was not very fast. Time Machine backups were estimating at 20 hours! I replaced it with a "Seagate FireCuda 530R SSD 1TB Internal Solid State Drive - M.2 PCIe Gen4 ×4 NVMe 1.4, speeds up to 7400MB" & as you'll see in the picture, I am now getting speeds almost as fast as a Samsung EVO Plus SSD. In addition, I am going through a Caldigit Thunderbolt 4 dock, not plugged directly into my 2025 Mac Mini. So this device can definitely, with the right SSD, deliver the speed.

Works like a charm. No heating issue observed so far. Using WD SN770 2TB with my mac studio m1 max. Giving expected read and write speeds. Value for money product.

Wish I could give this a better review. Seemed to work for awhile, but once I got deep into video editing it seems to overheat and unmount from my MacBook Pro M2 Max.
