- 90MB/s read speed

Who it's for
Owners of dash cams, security cameras, or trail cameras who need a card built for constant loop recording rather than occasional photo storage. Less suited to anyone chasing maximum rated speed for professional video work.
What buyers say
From Amazon customer reviews.
Most buyers reported the card working immediately with no setup trouble, handling continuous 1080p recording without dropped frames, and one specifically confirmed it running in a Eufy doorbell camera. The one clear complaint was a card that stopped working after the owner deleted files and reformatted it for reuse; another reviewer noted formatted capacity comes out around 110GB rather than the full 128GB label.
Strengths and trade-offs
Drawn from this product's published specifications.
- One reviewer's card stopped working after a reformat and reinsertion
- Usable capacity lands closer to 110GB than the 128GB label
- 90MB/s read speed is not benchmarked for 4K recording
