FAQs

Is this card suitable for 4K video recording?

Yes. The V30 video speed class guarantees a minimum sustained write speed of 50 MB/s, which is sufficient for standard 4K video recording on most DSLR and mirrorless cameras. This helps prevent dropped frames or recording interruptions during longer takes. It is designed for stable data flow rather than short bursts of peak speed. For everyday 4K capture, it performs predictably.

How does Stable Stream technology help in real use?

Stable Stream technology keeps write speeds consistent, preventing fluctuations during recording. In practice, this matters most on longer clips, where speed dips can cause the camera to stop recording. The card maintains a steady data rate, which is especially useful for interviews, events, or continuous shooting. It prioritises reliability over headline speed figures.

Is the card durable enough for outdoor work and travel?

The card is built to handle rough handling and challenging conditions. It is shockproof, waterproof, X-ray proof, magnetic proof and protected against static discharge. It also operates across a wide temperature range, so it remains usable in both hot and cold weather. This makes it a sensible choice for regular field use rather than studio-only storage.
