Overview
Drone pilots, action camera users and phone photographers get a microSDXC card rated for ultra HD video and app loading, plus an adapter for full size SD slots. The card is built to handle heat, cold, water, shock and airport x-rays.
Fast reads cut offload time for large photo and video files, and the video speed class supports steady recording. The rated speeds depend on the host device, so cameras and readers without matching support run slower.
Who it's for
Creators recording ultra HD clips outdoors get a card built for rough conditions with fast offloads. Owners of older devices that cannot use the higher speeds will not see the benefit.
Pros and cons
- Fast reads for quick offloads
- Video speed rating for ultra HD recording
- A2 rating for apps
- Adapter for full size SD slots
- Top speeds need a compatible device
- Memory zone app only on Google Play
- No warranty term listed
Performance notes
Transfer time depends on the reader: the rated read speed requires a device built to reach it, and a basic reader falls back to slower rates. Recording reliability rests on the card's sustained write class, which supports high bitrate video. App launches benefit from the application class.
