4.2 Installation Steps (General)
- Prepare Your Workspace: Work on a clean, well-lit surface. Ensure you have the necessary tools (e.g., small Phillips or Torx screwdriver, anti-static wrist strap).
- Power Down: Completely shut down your device and disconnect it from all power sources.
- Access the M.2 Slot: Carefully open your device's casing to access the M.2 slot. Refer to your device's service manual for exact instructions on how to do this.
- Remove Existing SSD (if applicable): If replacing an existing SSD, unscrew the retaining screw and gently slide the old SSD out of the slot.
- Install the S630 SSD: Align the notch on the S630 SSD with the key in the M.2 slot. Gently insert the SSD into the slot at an angle (usually 30 degrees) until it is fully seated.
- Secure the SSD: Push the SSD down until it is parallel with the motherboard and secure it with the retaining screw.
- Reassemble Device: Carefully close your device's casing.
- Power On: Reconnect power and turn on your device.
5. Operating Instructions
After physical installation, the SSD needs to be recognized and prepared by your operating system.
5.1 Initializing and Formatting the SSD
For a new SSD, you will typically need to initialize and format it before it can be used for storage. The process varies slightly depending on your operating system (Windows, Linux, SteamOS, etc.).
- Windows: Open Disk Management (right-click Start button > Disk Management). Locate the new SSD, right-click it, and select 'Initialize Disk'. Choose GPT (GUID Partition Table) for modern systems. Then, right-click the unallocated space, select 'New Simple Volume', and follow the wizard to format it (NTFS recommended).
- Steam Deck / ROG Ally: These devices typically have built-in utilities or prompts to format new storage devices upon boot. Follow the on-screen instructions.
- Other OS: Consult your operating system's documentation for instructions on disk initialization and formatting.
5.2 Performance
The fanxiang S630 1TB NVMe SSD offers sequential read speeds up to 5000 MB/s and sequential write speeds up to 3600 MB/s on PCIe Gen 4x4 compatible systems. Performance may vary based on system hardware, software, usage, and other factors. When used with PCIe 3.0 interfaces, speeds will be limited to approximately 3500 MB/s.
6. Maintenance
The fanxiang S630 SSD is designed for durability and reliability with minimal maintenance required. However, following these guidelines can help ensure optimal performance and longevity.
6.1 Thermal Management
The S630 SSD features a graphene heat dissipation sticker on its surface, acting as an ultra-thin heat sink. This design helps to effectively reduce heat generated during use, improving overall performance and stability.

Ensure your device has adequate airflow to further assist in heat dissipation, especially during prolonged heavy workloads.
6.2 Firmware Updates
Periodically check the fanxiang official website for any available firmware updates for your S630 SSD. Firmware updates can improve performance, stability, and compatibility. Follow the instructions provided with the firmware update carefully.
6.3 Data Backup
Regularly back up important data stored on your SSD to another storage device. While SSDs are highly reliable, no storage device is immune to failure.
7. Troubleshooting
If you encounter issues with your fanxiang S630 SSD, try the following troubleshooting steps:
- SSD Not Detected:
- Ensure the SSD is correctly seated in the M.2 slot.
- Check your device's BIOS/UEFI settings to confirm the M.2 slot is enabled and configured correctly (e.g., NVMe mode).
- Try the SSD in another compatible device or M.2 slot if available to rule out a device-specific issue.
- Verify that the SSD has been initialized and formatted by the operating system (refer to Section 5.1).
- Slow Performance:
- Confirm your device's M.2 slot supports PCIe Gen 4x4. If it's PCIe Gen 3.0, speeds will be limited to approximately 3500 MB/s, which is expected.
- Ensure your operating system and drivers are up to date.
- Check for excessive background processes or high CPU/RAM usage that might impact SSD performance.
- Monitor SSD temperature. High temperatures can lead to thermal throttling, reducing performance. Ensure proper cooling.
- System Instability/Crashes:
- Ensure the SSD is securely installed.
- Check for any conflicting drivers or software.
- Run a diagnostic tool (if available from fanxiang or your OS) to check the SSD's health.
If these steps do not resolve the issue, please contact fanxiang customer support (refer to Section 9).
