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.

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.

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 was having a hard time deciding which enclosure to buy. I decided at last minute to try this one. it is very easy to install. if you have a gen 4 nvme SSD Western digital hard drive then this enclosure is cool to the touch. I am getting 2600 to 2800 for speeds. this enclosure is really fast with just a 10 GB file in 5 seconds tranfers speeds. This was the cheapest thunderbolt enclosure that I could find on amazon. I am impress it come with a real thunderbolt 4 cable. I highly recommend this encloure

I bought this Thunderbolt 3 SSD enclosure (Model B0DD34LH8R) to upgrade my Mac Mini M4, which came with only 256 GB of storage. I paired it with a 2 TB WD Black M.2 SSD, applied the thermal pad(both side of the ssd) (heat tape), closed the case, and cloned my internal SSD using Carbon Copy Cloner (CCC). After switching the boot drive, my Mac now runs from the external SSD smoothly — effectively turning it into a 2 TB Mac Mini without paying Apple’s huge storage premium.Performance is excellent — I get around 2800 MB/s read and write speeds, which matches the Mac’s internal drive speed since it’s already throttled around that level. Thunderbolt 3’s 40 Gbps bandwidth is fully utilized.However, the product description says it has a cooling fan, but it actually doesn’t. That’s misleading. Fortunately, the aluminum body and heat pad manage temperatures decently, but under heavy transfers it can get warm.✅ Pros:True Thunderbolt 3 performance (~2800 MB/s)Solid aluminum body and premium buildEasy setup and bootable on macOS⚠️ Cons:No fan despite the claimGets warm during long transfersOverall, still a great enclosure for Mac users, but the missing fan description needs correction.
