Our verdict

A 4K-rated SDXC card for cameras and drones that comes with a mini case and a long warranty. Read speed is listed two ways, so rely on the V30 class for sustained video.

Overview

A camera owner who shoots high-resolution video gets a full-size SDXC card rated for 4K and marked with its speed ratings. It resists magnets, water and X-rays, and the pack includes a mini case.

The reason to buy is a high-rated video card with protection claims and lengthy coverage. The limit is the mismatch between the title and spec table on read speed, and the lack of a stated write figure beyond the media speed entry. Check that your camera takes SDXC.

Who it's for

Digital cameras, camcorders and action rigs that take full-size cards are the use. Phones and handheld devices with a microSD slot are not served by this format.

Pros and cons

Pros
  • Video speed class for 4K
  • Magnetic, water and X-ray proofing
  • Mini case included
  • Long warranty term
Cons
  • Read speed listed two ways
  • Write speed not stated plainly
  • Full-size format only

Performance notes

The video speed class guarantees a minimum sustained write rate, which matters more for steady 4K recording than the headline read speed. Read speed shows up when copying files to a computer.
