6. Maintenance
To ensure the longevity and optimal performance of your OWC Aura Ultra III SSD, consider the following maintenance tips:
- Firmware Updates: Periodically check the OWC website for any available firmware updates for your SSD. Firmware updates can improve performance, stability, and compatibility.

- TRIM Support: Ensure your operating system has TRIM enabled. TRIM helps the SSD manage its data blocks more efficiently, maintaining performance over time.
- Keep Cool: While the Aura Ultra III features thermal cooling, ensure adequate airflow around the drive, especially in high-performance scenarios or when used in an enclosure.
7. Troubleshooting
If you encounter issues with your OWC Aura Ultra III SSD, refer to the following common troubleshooting steps:
- SSD Not Detected:
- Check physical connections: Ensure the SSD is correctly seated in the M.2 slot or external enclosure.
- Verify BIOS/UEFI settings: Confirm that the M.2 slot is enabled in your system's BIOS/UEFI settings.
- Check Disk Management (Windows) or Disk Utility (macOS): The drive may need to be initialized and formatted.
- Slow Performance:
- Ensure the SSD is installed in a PCIe 3.0 compatible slot or enclosure to achieve advertised speeds.
- Verify TRIM is enabled in your operating system.
- Check for background processes consuming resources.
- Ensure your system drivers (chipset, NVMe) are up to date.
- System Instability/Crashes:
- Ensure the SSD firmware is up to date.
- Check system temperatures to prevent overheating.
- Run a diagnostic tool (if available from OWC) to check the SSD's health.
