Key Features

Superior Heat Dissipation, Keeping Cool at All Times: This NVME Enclosure features UGREEN Exclusive Triple Heat Dissipation Mechanism. The pure aluminum alloy casing provides excellent heat conductivity, while the silicone thermal pad absorbs and disperses the heat generated by the hard drive. The high-speed cooling fan accelerates the heat dissipation process, effectively reducing the hard drive temperature and improving its stability and reliability
Intelligent Cooling, Peace of Mind in Use: This M.2 SSD Enclosure is equipped with a PWM turbo high-speed fan, which can precisely control the fan speed and automatically adjust it to maintain normal temperatures. This not only protects the hard drive but also extends its lifespan. Additionally, the fan operates at a relatively low noise level, providing you with a comfortable user experience
Lightning Fast Transfers, Enjoy Efficient Living: With the built-in ASM2464PD chip, support for UASP acceleration protocol, and equipped with a USB4-compatible Type-C interface, this 40Gbps M.2 NVME SSD Enclosure is compatible with USB4/3.2/3.1/3.0/2.0 & Thunderbolt 3/4. Note：Thunderbolt 4 speeds require Thunderbolt 4 cables and interfaces. Other interfaces can only reach the highest speed of the corresponding interface
Widely Compatible, Explore More Possibilities: The 40Gbps Macbook SSD Enclosure is the preferred choice for gamers, video editors, photographers, and office workers. It supports M/B+M key NVMe solid-state drives with a maximum capacity of 4TB. It is compatible with sizes including 2230/2242/2260/2280, and it is suitable for Windows/Mac OS/Linux/Android systems (Note： Does not support SSD with heatsink and M.2 PCIE 5.0 SSD)
Self-Monitoring, Ensuring Secure and Reliable Backup: The S.M.A.R.T. technology enables timely detection of the hard drive's operational status, while the TRIM command function optimizes the performance of the solid-state drive. The USB4 NVME Enclosure facilitates self-monitoring, ensuring the security and stability of your data transfers. Additionally, the equipped silicone case effectively mitigates the impact on the hard drive enclosure
