6.1 Durability and Care
The SSD features an IP65 rating for water and dust resistance. This means it is tested to withstand water flow (30 kPa) at 3 minutes, and limited dust contact does not interfere with operation. For optimal performance and longevity, ensure the device is clean and dry before use, especially after exposure to water or dust.

6.2 Safe Ejection
Always safely eject the SSD from your computer before disconnecting it to prevent data corruption. Follow your operating system's guidelines for safe hardware removal.
6.3 Firmware Updates
Ensure your SSD's firmware is up-to-date for optimal performance and compatibility. Check the official SanDisk support website periodically for available firmware updates and installation instructions.
7. Troubleshooting
7.1 SSD Not Recognized
- Ensure the USB cable is securely connected to both the SSD and your device.
- Try a different USB port on your device.
- Test with the alternative USB cable provided (USB-C to USB-A or USB-C to USB-C).
- Restart your computer or device.
- Check your device's Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but uninitialized or unformatted.
7.2 Slow Transfer Speeds
- Ensure your device's USB port supports USB 3.2 Gen 2x2 for maximum speeds. Older USB ports will result in lower transfer rates.
- Verify that your operating system and drivers are up-to-date.
- Avoid transferring many small files simultaneously, as this can reduce overall speed compared to large single files.
- Close other applications that might be using system resources or disk I/O.
7.3 Drive Gets Warm During Use
It is normal for the SSD to become warm during extended periods of high-speed data transfer. The forged aluminum chassis is designed to dissipate heat and maintain performance. If the drive becomes excessively hot or performance degrades significantly, ensure it has adequate airflow and is not covered.
