4. 操作說明
4.1. 連接到主機設備
Connect the ACASIS SSD enclosure to your computer or compatible device using the provided 40Gbps USB-C cable. Ensure the connection is secure. The enclosure is plug-and-play, meaning it should be recognized automatically by your operating system.
4.2 資料傳輸和效能
The ACASIS TBU401 Pro supports up to 40Gbps data transfer speeds. Actual speeds may vary depending on your SSD, host device, and operating system. For optimal performance, ensure your device supports USB4 or Thunderbolt 3/4.

4.3. 冷卻風扇運轉
The built-in cooling fan automatically activates to dissipate heat during intensive operations, helping to maintain stable performance and prevent thermal throttling. The fan operates quietly to minimize disturbance.
4.4. SSD Formatting and Speed Testing
For new SSDs, you may need to format the drive before use. The choice of file system (e.g., ExFAT, APFS) can impact performance and compatibility across different operating systems. For example, APFS generally offers faster speeds on Apple Silicon Macs compared to ExFAT, but ExFAT provides broader compatibility across Windows, macOS, and Linux systems.

- Always safely eject the drive from your operating system before disconnecting the cable to prevent data corruption.
7。 故障排除
If you encounter issues with your ACASIS SSD Enclosure, refer to the following common problems and solutions:
7.1. 驅動器無法識別
- 確保固態硬碟已正確安裝並牢固地固定在機殼內。
- Try connecting the enclosure to a different USB/Thunderbolt port on your device.
- 如果有其他數據線,請嘗試使用另一條數據線。
- Check Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but unformatted. Format if necessary.
7.2 資料傳輸速度慢
- Verify that your host device's port supports 40Gbps (USB4 or Thunderbolt 3/4).
- Ensure you are using the provided 40Gbps cable.
- Check the SSD's health and performance.
- 關閉所有可能佔用系統資源或磁碟 I/O 的背景應用程式。
- For Apple Silicon Macs, using APFS format generally yields faster speeds than ExFAT.
7.3. 過熱
- Ensure the thermal pads are correctly placed on the SSD.
- Verify that the cooling fan is operating (a slight hum or airflow might be noticeable).
