40Gbps Thunderbolt NVMe Enclosure
The Acasis TBU405 is a single-bay M.2 NVMe enclosure that connects through a Thunderbolt 3 or Thunderbolt 4 port at up to 40Gbps. An Intel JHL7440 controller delivers sequential reads up to 2800MB/s and writes up to 2500MB/s. The aluminium shell and thermal pad dissipate heat without a fan. It accepts 2280 B+M and M-key drives up to 8TB and works with Windows, macOS and Linux.
Professionals who need portable.
This enclosure suits video editors, photographers and developers who move large project files between Thunderbolt-equipped laptops and desktops. Plug-and-play operation and hot-swap support keep workflows simple. It is not for users whose computers lack a Thunderbolt 3 or Thunderbolt 4 port, because USB-C connections fall back to lower USB speeds and cannot reach the rated throughput.
Thunderbolt 3 or Thunderbolt 4 host port required
The single specification that decides compatibility is the presence of a genuine Thunderbolt 3 or Thunderbolt 4 interface on the host. Without it the enclosure reverts to USB 2.0, 3.0, 3.1 or 3.2 speeds, which are far below the 40Gbps design target. Verify the port on your device before purchase.

Questions sur cet article
What real-world throughput can I expect from the 40 Gbps rating once the enclosure is in my machine?
The enclosure uses an Intel JHL7440 controller to deliver up to 2800 MB/s reads and 2500 MB/s writes with a compatible NVMe drive.
Which Thunderbolt or USB standard caps the 40 Gbps link in practice?
Thunderbolt 3, Thunderbolt 4 and USB4 all support the full 40 Gbps bandwidth; older USB 3.2, 3.1, 3.0 or 2.0 ports will run at their own lower limits.
What physical SSD sizes and keys does the tray accept for mounting?
It fits a single 2280 NVMe drive using M-key or B+M key PCIe, secured by the included thermal pad and screw.
