Overview
Slipping into a camera slot, this SDXC card stores stills and clips, and it reads at the rated speed on UHS-I devices. It is listed as temperature proof, water proof and X-ray proof.
A long day of shooting or travel fits on one big card, and the rugged ratings help in bags and airports. The limitation is the speed class, which is stated for photos and Full HD video only.
Who it's for
A travel photographer or a hobbyist with an older camera that uses UHS-I cards is the usual owner. Videographers who need sustained fast writing should choose a higher class.
Pros and cons
- Fast read speed
- Water and temperature proof
- Long limited warranty
- 4K recording not claimed
- Write speed not listed
- Single card in the pack
- Slot fit details not listed
Performance notes
Read speed governs how fast files move to a computer, while the speed class gives a minimum write rate for video. A U1 rating guarantees enough for Full HD recording, not for the data rates of higher resolutions. Camera support for UHS-I decides whether the card reaches its rated read speed.
