Final thoughts
Ugreen’s tool-free aluminum alloy design got a premium feel. Nice to touch when cool. Warm to touch when in use. The aluminum acts as a heatsink to the M.2 SSD inside.

Good read & write speed using the Realtek RTL9210B chipset.

Great to use as an OTG drive for my daily use at work and at home.
