The short version
UGREEN's 40Gbps enclosure turns an M.2 NVMe SSD into a portable drive over USB4, using an ASM2464PD controller and supporting 2230 to 2280 drives up to 4TB. An aluminum shell, thermal pad and PWM fan manage heat, which matters for sustained transfers. It does not support SATA M.2 drives. It suits people reusing a spare NVMe SSD who want USB4 speeds; UGREEN's page states no measured transfer rates, and no independent test was read here.
Pros
- ASM2464PD controller with USB4 support up to 40 Gbps
- Aluminum alloy shell, thermal pad and PWM fan for cooling
- Supports 2230, 2242, 2260 and 2280 NVMe drives up to 4TB
- TRIM and S.M.A.R.T. support, per UGREEN
Cons
- No support for SATA M.2 or mSATA drives
- UGREEN's page publishes no measured transfer speeds
- 4TB maximum drive capacity
Best for
- Reusing a spare NVMe SSD as a fast external drive
- USB4 or Thunderbolt laptop owners

Common questions
Does the UGREEN 40Gbps enclosure support SATA M.2 SSDs?
No. UGREEN says it supports NVMe drives with M or B+M keys and does not support SATA NGFF or mSATA SSDs.
What is the largest SSD it can hold?
UGREEN lists a maximum capacity of 4TB and physical sizes from 2230 to 2280.
Will it reach 40 Gbps on any laptop?
It needs a USB4 or Thunderbolt 3/4 port to negotiate 40 Gbps. On older USB 3 ports it runs at those ports' lower speeds.
