Product identity

The Freegene TBU 405 is a compact 40Gbps NVMe enclosure that accepts M.2 drives in 2230, 2242, 2260 and 2280 lengths. It connects to Windows, macOS and Linux hosts including M1 Pro and Max Macs and iPad Pro via USB4, USB 3.2, 3.1, 3.0 and 2.0. The JHL7440 certified dual-chip controller manages data flow and thermal load without an included SSD.

Thermal behaviour

The dual-chip design improves heat dissipation during sustained transfers so the enclosure stays stable under load. Power is drawn entirely from the host USB port with no external adapter required. Fanless construction keeps operation silent in office or travel environments.

Deciding specification

The 40Gbps USB4 interface enables sequential reads up to 2805MB/s and writes up to 2734MB/s with a compatible drive such as the Samsung 980 EVO Plus; actual throughput depends on the host controller and SSD. Buyers limited to USB 3.2 or earlier ports will not reach these peak figures.

Questions about this item

How do I install an M.2 2280 NVMe drive into the TBU 405 enclosure?

Open the enclosure, align the drive's key notch with the internal M.2 slot, insert at an angle, then press down and secure with the provided screw before closing the case.

What maintenance will the JHL7440 chipset enclosure need over time?

Keep the ventilation slots clear of dust using compressed air; the aluminium shell acts as a heatsink, so no thermal-pad replacement is required.

What limits sustained write speeds on the TBU 405 during long transfers?

Thermal throttling of the NVMe drive itself; the enclosure's dual-chip design and metal body dissipate heat, but extended writes will eventually hit the drive's own temperature ceiling.
