Review: When I originally received this enclosure it was missing the heat pad and the usb-c cable that was included was short and only capable of usb 2 speed so when I wrote my original review I complained about the low data speed (30MB/s) and the missing heat pads and only gave the product 3 stars. The enclosure was fine, the accessories were bad or missing. After a long email correspondence with Acacias Customer Support, which included pictures of what I received, they told me that the cable I got was not their cable and so I thought I might have received a device that had been shipped to someone else and returned without the heat pad and with a useless usb cable, and I ordered a replacement. The Acacias product package was not sealed so it was not possible to tell if it already had been opened. The replacement just came in and when I opened the package (it was also not sealed) it contained a proper Thunderbolt 4 cable and the heat pad, and when I tested it I received the kind of speeds I expected - about 2800 MB/s using the WD 1 TB 2280 memory. That makes it clear that I received the bad usb cable due to my original order having been returned to desertcart by another customer and not due to the fault of the vendor, so I have revised my review. This enclosure works very well, although it does get very warm and probably needs a cooling fan as well as the included heat pads. The speeds are everything I expected and the included Thunderbolt cable works properly. It is a bit short for me, but it is the length specified in the product description. I am happy with the replacement and feel capable of recommending it. If you want external drive speeds close to the speed of your computer memory consider this enclosure. --------------- I recently bought the version of this enclosure that contains a fan for cooling and when I tried to leave a review desertcart told me that I had already reviewed it, although that version was the version without the fan, so I am adding this review to the end of the original review. While the original enclosure is a great way of adding high speed memory to your system it suffered from one drawback and that is it needs cooling. I solved the problem by buying a small muffin fan and attaching it to the enclosure and, with that, it ran cool and I had no heat issues. This new enclosure solves that problem and I have replaced the version without the fan with this one. This is a first class enclosure with transfer speeds as high, if not higher, than the internal memory of my Mac M2 Mini. Repeated use of the Black Magic speed app showed no slowdowns due to thermal throttling so it is dependable and fast, even after long use. Thee are some minor issues. First, the manual that comes with the enclosure is the manual for the version without the fan so it contains no information about the cooling fan. There is a small button on the side of the enclosure to turn the fan on and off, but even when holding the unit next to my face I could not feel air moving. To be sure that the fan was working I had to hold it next to my ear, and I could hear it running. There is also a small LED on the side of the enclosure and it shows a constant light when the fan is running and a blinking light when the fan is not running. I have picked up the enclosure during the day and found it to be slightly warm while the old enclosure was hot to the touch without the muffin fan I attached. This is a great enclosure and I believe that it deserves the 5 stars I have given it.
