40 Gbps M.2 NVMe Enclosure

This aluminium enclosure accepts a single 2280 NVMe SSD up to 2 TB. It connects through a USB-C port that supports Thunderbolt 3, Thunderbolt 4 and USB 3.2 Gen 2x2. A built-in fan provides active cooling for sustained transfers.

40 Gbps Thunderbolt 4 and USB4 interface

The external Type-C connection delivers up to 40 Gbps bandwidth with Intel JHL7440 and JMicron JMS583 controllers. Using the supplied C-to-C cable enables the full 40 Gbps link, while the C-to-A cable limits throughput to 10 Gbps. USB 2.0 is not supported.

Suits users with Thunderbolt 3, 4 or USB4 hosts

Buyers whose computers only offer USB 3.2 Gen 2 or earlier will not reach the enclosure's peak speed. The single-bay design also means anyone needing multiple drives must look elsewhere.
