Nastavení
Installing the M.2 NVMe SSD
Pro instalaci disku M.2 NVMe SSD do skříně postupujte takto:
- Open the bottom cover: Gently slide the bottom cover of the enclosure in the direction indicated by the "OPEN" arrow until it detaches.
- Vložte disk M.2 SSD: Carefully align your M.2 NVMe SSD with the M-Key slot inside the enclosure and insert it firmly. Secure the SSD in place using one of the provided fixed rubber stoppers.
- Apply the thermal pad: Remove both protective films from a thermal pad. Place the thermal pad directly onto the installed M.2 SSD. This helps dissipate heat from the SSD to the aluminum enclosure.
- Close the bottom cover: Realign the bottom cover and slide it back into place until it clicks securely.

Údržba
The GRAUGEAR U4-40G01 features a fanless all-aluminum design for efficient heat dissipation and silent operation. Minimal maintenance is required to ensure optimal performance and longevity:
- Čištění: Periodically wipe the exterior of the enclosure with a soft, dry cloth to remove dust and fingerprints. Avoid using liquid cleaners or abrasive materials.
- Tepelný management: Hliníkové casing acts as a heatsink. Ensure adequate airflow around the enclosure, especially during prolonged high-speed transfers, to facilitate heat dissipation.
- Podmínky prostředí: Avoid exposing the enclosure to extreme temperatures, direct sunlight, high humidity, or dusty environments.
- Zacházení: While durable, avoid dropping or subjecting the enclosure to strong impacts, which could damage the internal SSD or components.
Odstraňování problémů
Low Transfer Speeds
- Host Port Verification: Ensure your computer's USB port supports USB4 or Thunderbolt 4. Connecting to older USB standards (e.g., USB 3.2 Gen1/Gen2, USB 3.0) will limit speeds to their respective maximums (e.g., 5Gbps, 10Gbps, 20Gbps).
- SSD Performance: The actual speed is limited by the installed M.2 NVMe SSD. For speeds exceeding 3000MB/s, a high-performance PCIe Gen4 NVMe SSD is recommended.
- Kvalita kabelu: Use the provided high-quality USB Type-C cable. Lower quality or longer cables can degrade performance.
- Tepelné škrcení: Although designed for efficient cooling, prolonged heavy workloads can cause the SSD to heat up. Ensure the thermal pad is correctly installed and the enclosure has adequate ventilation.
Disk nebyl detekován
- Sedadla SSD: Re-open the enclosure and ensure the M.2 SSD is fully and correctly seated in its slot, secured by the rubber stopper.
- Kabelové připojení: Verify that the USB cable is securely connected to both the enclosure and the host device.
- Disk Initialization/Formatting: For new SSDs, the drive may need to be initialized and formatted in your operating system's Disk Management (Windows) or Disk Utility (macOS) before it appears in File Průzkumník/Vyhledávač.
- Test with Another Port/Device: Try connecting the enclosure to a different USB port on your computer or to another compatible device to determine if the issue is with the port or the enclosure itself.
