4.2 Installing the M.2 NVMe SSD
- With the enclosure open, carefully insert your M-Key NVMe SSD into the M.2 slot. Ensure the SSD is aligned correctly with the connector.
- Secure the SSD using the provided snap-on fastener.
- Apply the thermal pad to the SSD, then place the heatsink on top of the thermal pad for optimal heat dissipation.
Note: This enclosure supports M-Key NVMe SSDs of sizes 2230, 2242, 2260, and 2280. It is not compatible with SATA-based M.2 SSDs (B-Key or B+M Key SATA) or some specific NVMe SSD models like Crucial P3 Plus, WD Black SN750, and Samsung 970 EVO Plus.

4.3 Closing the Enclosure
- Once the SSD and heatsink are securely in place, slide the top cover back until it clicks into position.
5. Operating Instructions
5.1 Connecting to a Host Device
Use the provided USB-C to A/C cable to connect the enclosure to your computer or compatible host device. The enclosure supports various connection types:
- USB4 / Thunderbolt 3/4: For maximum transfer speeds of up to 40Gbps.
- USB 3.2 / 3.1 / 3.0: Backward compatible, with speeds up to 10Gbps.
Upon connection, the enclosure should be recognized by your operating system as an external storage device. You may need to initialize and format the SSD if it is new or unformatted.

6. Heat Dissipation and Performance
The ORICO enclosure is engineered with multiple heat dissipation mechanisms to ensure stable performance, especially during prolonged high-speed operations:
- Aluminum Alloy Body: The CNC-machined aluminum casing acts as a large heatsink, efficiently conducting heat away from the SSD.
- Built-in Cooling Fan: A silent fan actively circulates air to prevent heat buildup.
- Dual-End Airflow Vents: Designed to optimize air circulation through the enclosure.
- Thermal Pad and Heatsink: The included accessories further enhance heat transfer from the SSD to the enclosure.
These combined features help maintain lower operating temperatures, preventing thermal throttling and ensuring consistent high-speed data transfer.
7. Compatibility
7.1 SSD Compatibility
- Supported: M-Key NVMe SSDs (PCIe protocol) in sizes 2230, 2242, 2260, and 2280. Maximum capacity up to 8TB.
- Not Compatible: SATA-based M.2 SSDs (B-Key or B+M Key SATA).
- Specific NVMe SSDs with known compatibility issues: Crucial P3 Plus, WD Black SN750, and Samsung 970 EVO Plus.
7.2 Host Device and System Compatibility
- Host Devices: Compatible with USB4 and Thunderbolt 3/4 host devices (e.g., Mac M1/M2, Intel 12th generation or newer laptops). Backward compatible with USB 3.2/3.1/3.0 ports.
- Operating Systems: Windows, Android, Linux, Mac OS, Chrome OS, iPadOS.
Note: Older Thunderbolt versions and some USB ports may not support the full 40Gbps speed. Ensure your host device supports the desired transfer rate for optimal performance.

8. Troubleshooting
- Device Not Recognized:
- Ensure the SSD is correctly seated in the enclosure and the enclosure is properly closed.
- Try connecting to a different USB/Thunderbolt port on your host device.
- Test with a different cable if available.
- Verify the SSD is an M-Key NVMe type and not a SATA M.2 SSD.
- Check Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but uninitialized/unformatted.
- Slow Transfer Speeds:
- Ensure your host device's port supports 40Gbps (USB4 or Thunderbolt 3/4). Connecting to a USB 3.0/3.1/3.2 port will result in lower speeds.
- Verify the SSD itself is capable of high speeds.
- Check for background processes that might be consuming system resources.
- Ensure proper heat dissipation by checking if the fan is operating and the heatsink is correctly installed. Overheating can lead to performance throttling.
- Enclosure Overheating:
- Confirm the thermal pad and heatsink are correctly installed on the SSD.
- Ensure the cooling fan is not obstructed.
- Avoid placing the enclosure in confined spaces that restrict airflow.
