Operating Instructions
1. Connecting to a Host Device
Connect the enclosure to your computer or compatible device using the provided USB-C cable. The enclosure supports a wide range of interfaces:
- USB4 / Thunderbolt 4: For optimal 40Gbps transfer speeds.
- Thunderbolt 3 / USB 3.2 Gen 2x2: Speeds up to 20Gbps.
- USB 3.2 Gen 2: Speeds up to 10Gbps.
- USB 3.2 Gen 1 / USB 3.0: Speeds up to 5Gbps.
- USB 2.0: Speeds up to 480Mbps.
To achieve the maximum 40Gbps transfer speeds, your host device must support USB4 or Thunderbolt 4, and you must use a compatible USB4-certified cable and port. Actual performance may vary based on the SSD's read/write speed and your device's hardware configuration.

Troubleshooting
- Top Cover Difficult to Close: Ensure the "USB" marking on the top cover is aligned with the side that has the USB port. Incorrect alignment can prevent proper closure.
- Not Achieving 40Gbps Speed: To reach 40Gbps, your host device must support USB4 or Thunderbolt 4, and you must use a compatible USB4-certified cable and port. Older ports (e.g., USB 3.2, Thunderbolt 3) will limit speeds. The SSD's read/write speed and your system's hardware configuration also affect performance.
- Backward Compatibility: The enclosure is backward compatible with USB 3.2 Gen 2/Gen 1 and USB 2.0, but transfer speeds will be limited to the maximum supported by those ports.
- SSD Not Included: This product does not include an NVMe SSD. You need to purchase and install an SSD separately.
