Compared side by side
The UGREEN 40Gbps M.2 NVMe SSD Enclosure with Cooling Fan (USB4 appears in this table next to models from other brands:
Who it's for
Anyone copying hundreds of gigabytes at a time (video, backups) from a Gen4 NVMe drive over a Thunderbolt or USB4 port.
Caveats
- UGREEN publishes no sustained-transfer or temperature figures of its own; PCWorld's 450 GB write ran with no thermal trouble and IT-Connect saw 43 °C, stable.
- Not tool-free despite one UGREEN title: one top screw, screwdriver in the box (PCWorld, IT-Connect). Max capacity is listed as 4 TB on UGREEN's EU page while reviewers ran an 8 TB drive.
- 40 Gb/s needs a USB4 or Thunderbolt port and the included short cable; a USB 3.2 port gives 10 Gb/s.
