- Verify your SSD itself supports 10Gbps speeds.
- Check the integrity of the USB cable.
- Ensure the thermal pad is correctly installed to prevent thermal throttling.
- Enclosure Overheating:
- Ensure the thermal pad is correctly installed between the SSD and the aluminum casing.
- Avoid prolonged heavy data transfers in poorly ventilated areas.
