Overview
A GoPro owner, drone pilot or dash cam user storing 4K footage is the target for this microSDXC card. It carries the UHS-I U3, A2 and V30 speed marks and is described as waterproof and X-ray proof.
The reason to buy is the sustained write rating needed for 4K video, plus a free recovery service if files are lost. The limit is the capacity, which is modest for heavy 4K recording, and UHS-I tops out below the newer card classes.
Who it's for
Action cameras, drones, dash cams, security cameras and handhelds that use microSDXC are the intended hosts. Photographers who need a full-size SD card, or anyone who wants to store hours of 4K without swapping cards, should look at larger capacities.
Pros and cons
- Rated for 4K video recording
- Waterproof and X-ray proof
- Long warranty term
- Free data recovery offer
- Capacity limits long 4K sessions
- UHS-I interface, not UHS-II
- Adapter not listed in the specs
- Write speed is half the read speed
Performance notes
The V30 and U3 marks promise a minimum sustained write speed, which is what protects 4K video from dropped frames. Peak read speed matters for copying footage off the card, while the write rating matters for recording, and the host device also has to support the card class.
