The 40Gbps figure is the reason this UGREEN sits at the top of our list, but it comes with a condition: you need USB4 or Thunderbolt on the host to see it. On those ports the ASM2464PD controller and 3,600MB/s ceiling put it in a different class from the 10Gbps cases here, which is why we recommend it first for large video files, game libraries, and anyone buying a laptop with USB4.
The cooling is not decorative. The double-sided aluminum fins and thermal pad give both the drive and the controller somewhere to send heat during long writes; that matters because a fast SSD that throttles is just a slower SSD with a bigger number on the box. We also like that the case takes 2230 through 2280 drives up to 8TB, so it can follow a drive from a handheld into a desktop.
The screw-in assembly takes a few minutes, and the included disassembly kit has what you need; frequent drive swappers may prefer a clamshell. This is a desk or backpack enclosure rather than a pocket accessory, and the aluminum body is the part that makes it feel worth the space. We like the way it turns a bare drive into something that feels like a finished portable SSD.
Pros
- 40Gbps ceiling for USB4 and Thunderbolt
- Finned aluminum body and thermal pad
- Fits 2230–2280 drives up to 8TB
- Installs with included disassembly kit
Cons
- Door feels less sturdy than the body
- Heavier than most 10Gbps cases
For a USB4 or Thunderbolt laptop, this is the NVMe enclosure we recommend first: it has the speed ceiling, cooling, and drive range to justify its size.
