worst product ever, fan not working. burnt smell coming.

The speed is very good, and heat dissipation is acceptable if air flow is not obstructed in any way. My main complaint, and the reason I stopped using it daily, is excessive power consumption when it is plugged in but not being accessed. I can't be sure, but when connected to my MacBook Pro M4Pro, the enclosure fan ran continuously and the SSD *may* have been drawing power even when not having been used for an extended period. That is, it did not seem to have an effective sleep or low power mode.

Item came in nicely packaged. You slide the lid off to place your SSD card in it. I inserted a 4TB SSD that I used on my Mac Mini M4. I also bought a doc that has an encasement for a SSD card that plugs into the Mac Mini, which can save spaces. The doc stopped working and reading my card, so I thought I'd try this encasement that was simple and with no bells and whistles so to speak. It does have an internal fan, which I thought was good since it reads/writes at 40Gbps, and I know they can get pretty warm when you load files onto it. This encasement worked wonderfully and then it stopped reading again and ejecting. Found out that the Apple Mac Mini's don't have enough power to power the encasement/SSD card, so I had to connect it to a hub and now it's great. I'm thinking my doc was probably still good as well but the mac mini couldn't power it along with other external drives I had connected to it. I really like the look of the encasement. It still gets hot when you load large files like video, but it does it super fast. You will need to place it somewhere cool and out in the open. Do not lay it on anything metal as the metal will not allow it to cool.

I had repeated overheating with this item when hooked to brand new mac mini m4. Using Samsung 990 NVME drive evo the temperature got to 160 F all the time. This was a consistent issue when hooked to thunderbolt4 and using both manufacturer cable and replacement thunderbolt 5 cable. The plastic case and ill placed fan are an oven. Putting an external fan on it dropped it to 125. My replacement Acasis thunderbolt 4 case does not go over 104 without a supplemental extenal fan. Poor thermal design characteristics. Bad choice for high speed Thunderbolt use. Overheating caused power supply overloading and repeated umount errors from Mac mini. The Orico unit is unsuitable for use as a thunderbolt 4 external item. It works ok on thunderbolt 3 or 10Gbps Usb.

Bonne vitesse et bonne qualité des matériaux sauf ventilateur assez bruyant.

Installed Win10 (clone of my full system previously in the laptop) and it works just fine.
