Important Note

For NVMe M.2 2280 SSD only, SATA M.2 SSD is not supported.
Due to different systems and testing application algorithms, the read and write speed test results on macOS system will be slower than on Windows system.
To utilize the full bandwidth of the USB4 interface, please install high performance NVMe M.2 SSD into the enclosure, PCIe 4.0 NVMe M.2 SSDs are recommended.
The metal case will turn to a relatively high temperature during operation, which is normal and will not cause damage to your SSD as the metal case will effectively absorb heat.
