Overview
A 128GB microSDXC card rated UHS-I U3, A2, and V30, built for 4K recording in action cameras, drones, and the Nintendo Switch, with read speeds up to 100 MB/s and write speeds up to 50 MB/s.
The A2 rating matters mainly for phones and tablets running apps directly off the card, while V30 and U3 are what sustain 4K video without dropped frames. Gigastone backs it with a 5-year free data recovery service, a detail worth knowing before assuming a failed card means lost footage for good.
- 128GB microSDXC, UHS-I U3, A2, V30, Class 10
- Up to 100 MB/s read, 50 MB/s write
- Rated for 4K recording in GoPro, DJI, and Switch use
- 5-year free data recovery service included
Who it's for
Works for GoPro, DJI, and Switch owners needing steady 4K write speeds, and for anyone expanding phone storage where app-load speed matters. Not the pick for professional cinema cameras needing sustained write speeds above what V30 guarantees.
Pros and cons
- Sustains 4K recording in dashcams and action cameras
- Sometimes ships bundled with an SD card reader
- 5-year data recovery service backs up the card
- Peak read speed is not what governs video recording
Performance notes
V30 guarantees a minimum sustained write speed for continuous 4K recording, which is the number that matters for dashcams and action cameras rather than the peak 100 MB/s read figure. The A2 rating adds faster random access for app loading when the card is used as phone or tablet storage rather than for video.
