The theoretical transmission bandwidth is 40Gbps and only supports Thunderbolt 4/3 and USB 4 interface protocols. Its shell is similar to the TBU405, with many stripes to speed up heat dissipation. At the same time, this product is also tool-free to install and use.

3.TBU401

This Thunderbolt SSD enclosure is similar to TB34 in appearance, both are silver, and the size is almost the same, but it is heavier in weight, about 125g.

TBU405 is the same as the aforementioned Thunderbolt SSD casing, compatible with Thunderbolt 4/3, USB4.0/3.2/3.1/3.0/2.0 interfaces, supports NVMe protocol, 22*80 length, and M.2 interface SSD with a maximum capacity of 8TB. It is different from TBU401, its color is dark gray or light gray, and its aluminum alloy shell has more stripes, which will help it dissipate heat better.
