Setup
General Installation Notes
Before beginning installation, ensure your device (PS5 or PC) is powered off and disconnected from the power source. Handle the SSD by its edges to avoid touching the gold connectors or components. Static electricity can damage electronic components, so consider using an anti-static wrist strap or grounding yourself before handling the SSD.
Physical Installation (Heatsink Assembly)
The fanxiang S660 comes with a pre-installed heatsink. If you need to re-assemble or verify the heatsink installation, follow these steps:
- Choose one thick and one thin cooling pad from the included accessories.
- Tear off the plastic film from the thick thermal pad and place it on the heatsink base.
- Place the SSD onto the thermal pad, ensuring the chip faces upwards. Adjust its position so the screw holes and the M.2 interface are aligned.
- Tear off the plastic film from the thin thermal pad and stick it on the bottom of the heatsink cover.
- Insert one side of the heatsink cover into the slot of the base. After adjusting the position, press the other side of the heatsink cover firmly until you hear a "click," indicating it is securely in place.
- Fix the SSD with the heatsink installed using the screws or buckles provided with your motherboard or console.

General Maintenance Tips:
- Keep your system well-ventilated: Ensure adequate airflow around your PS5 or PC to assist with heat dissipation.
- Avoid extreme temperatures: Operate the SSD within recommended environmental temperature ranges.
- Regularly update system firmware: Keep your console or motherboard firmware updated to ensure compatibility and optimal performance.
- Perform TRIM operations: Modern operating systems typically handle TRIM automatically for SSDs, which helps maintain performance over time. Verify this setting if you experience performance degradation.
Troubleshooting
- SSD Not Recognized:
- Ensure the SSD is correctly seated in the M.2 slot.
- Verify that your system's BIOS/UEFI (for PC) or PS5 firmware is up to date.
- Check if the M.2 slot is enabled in your system's BIOS/UEFI settings (for PC).
- Slow Performance:
- Confirm that your system supports PCIe 4.0 to achieve maximum speeds. If using PCIe 3.0, speeds will be limited.
- Ensure the SSD is not overheating. Check system temperatures if possible.
- Verify that TRIM is enabled and functioning correctly.
- Ensure the SSD is not nearly full, as performance can degrade when storage is almost at capacity.
- Data Transfer Errors:
- Re-seat the SSD to ensure a stable connection.
- Check for any system errors or warnings related to storage devices.
