Compact 40Gbps NVMe enclosure for Thunderbolt hosts

The Acasis TBU405M1 wraps an M.2 2280 PCIe NVMe drive in a fan-less aluminium shell with a corrugated surface for passive cooling. A single USB-C port carries Thunderbolt 3, Thunderbolt 4 and USB4 traffic at up to 40Gbps and falls back through USB 3.2, 3.1, 3.0 and 2.0 without driver installation on Windows, macOS or Linux.

Suits creators who need peak bus speed.

Editors and engineers moving multi-gigabyte video or dataset files get the full 40Gbps pipe when the host has Thunderbolt 3, Thunderbolt 4 or USB4. Buyers whose SSDs include factory heatsinks must remove them or choose another enclosure because the internal clearance only accepts bare 2280 modules.

8TB single-drive limit decides capacity planning

The enclosure addresses one NVMe SSD up to 8TB, so the largest single module you can install defines the total storage. If your workflow demands more than 8TB in a single bus-powered device, this unit cannot meet that need.

商品問答

Which M.2 NVMe SSD sizes and keys does the TBU405M1 accept?

The enclosure fits 2280 M-key and B+M key PCIe NVMe drives up to 8TB; SSDs with pre-attached heatsinks will not fit.

What real-world speeds can I expect from the 40Gbps rating with a Samsung 980 EVO Plus?

Acasis lab tests on a MacBook Pro showed sequential reads up to 2805MB/s and writes up to 2734MB/s; actual throughput varies by host, OS and SSD.

How does the 40Gbps Type-C interface scale when connected to USB 3.2, 3.1, 3.0 or 2.0 ports?

The Intel JHL7440 controller negotiates down to each USB standard’s native ceiling, so the drive runs at the highest speed the port allows.
