Maintenance
To ensure the longevity and optimal performance of your UGREEN SSD enclosure, consider the following maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Avoid liquid cleaners or abrasive materials that could damage the finish.
- Handling: Handle the enclosure with care to prevent drops or impacts, which could damage the internal SSD or the enclosure itself.
- Storage: When not in use, store the enclosure in a cool, dry place away from direct sunlight and extreme temperatures.
- Disconnection: Always safely eject the device from your operating system before physically disconnecting it to prevent data corruption.
Troubleshooting
If you encounter issues with your UGREEN SSD enclosure, refer to the following common questions and solutions:
1. Why can't the enclosure reach 20Gbps?
This M.2 enclosure can only achieve up to 20Gbps transfer speeds when connected to a USB 3.2 Gen 2x2 (20Gbps) port. Other ports, including Thunderbolt 3 and Thunderbolt 4, are limited to a maximum of 10Gbps due to differences in data communication protocols. Ensure your host device's USB port supports USB 3.2 Gen 2x2 for maximum speeds.
2. Can this M.2 enclosure support 20Gbps with MacBook?
No, the enclosure will typically only reach 10Gbps on MacBooks. MacBooks generally feature Thunderbolt 3 or Thunderbolt 4 ports, which do not support 20Gbps when connected to this enclosure. The maximum speed will be limited by the Thunderbolt port's native USB compatibility, which is 10Gbps.
