Recommendations

For reliable performance, avoid filling the card to full capacity and periodically back up important data. Use the card in devices that support its speed classes for tasks such as 4K recording or running apps. If you plan to use the card in high-vibration or moisture-prone environments, ensure the device’s protective seals are intact and handle the card by its edges to minimise risk of physical damage.
