What this enclosure does

The Hetai Tech TBU42 turns an M.2 NVME solid-state drive into a portable Thunderbolt 3 drive. It also works as a USB 3.0 docking station for laptops running Windows or Mac. The unit ships with a 50cm cable and supports drives up to the 2280 form factor with M-key or B&M-key interfaces. It does not accept SATA protocol SSDs.

Sustained transfer behaviour

Thunderbolt 3 provides a 40Gbps link so large sequential reads and writes stay fast during long sessions. The aluminium body acts as a heatsink to keep the SSD cool under continuous load. Total power delivery is rated at 100W with 40W reserved for the hub portion, leaving 60W for laptop charging regardless of whether the hub is active.

Installation notes

Slide the NVME stick into the M-key slot, secure it with the included screw and close the tool-free cover. The enclosure is driver-free on supported operating systems. Remember that SATA M.2 drives will not work and the single Thunderbolt 3 port means you cannot daisy-chain another Thunderbolt device downstream.

Questions about this item

How warm or noisy does the TBU42 get when running an M.2 NVME drive all day?

The enclosure has no built-in fan, so it relies on passive cooling; under sustained load the aluminium body will feel warm but stays silent.

Which cables or ports must my laptop already have to use the TBU42 at 40Gbps?

A Thunderbolt 3 port is required for full 40Gbps speed and 60W PD charging; a plain USB 3.0 port will fall back to lower bandwidth.

Can I keep using my older SATA M.2 drives with the TBU42?

No, the TBU42 only accepts NVME protocol M.2 drives with M-key or B&M-key connectors; SATA M.2 drives are not supported.
