## Questions & Answers

**Q: Does this work with Sony rx100 camera**
A: If your camera accepts a 256GB micro SD card it will. The specifications on this card are very good.

**Q: Would this work on a dji pocket 2? thanks.**
A: it can support

**Q: Will it work with go pro hero 7 ?**
A: Yes

**Q: Will this work for my dji mini 3 pro?**
A: Yes it will, I own the same drone and it works fine in mine. However I shoot in 1080p because shooting at 4k in the type of subject that I was shooting I did have some frame drops or frame freezing. It’s like the card can’t write that large of files fast enough and store them, so it drops frames. But by me switching to 1080p, it has no problem and it doesn’t really matter switching to that file size unless you’re watching your videos on a super big screen T.V. or in an iMax theater. If that’s the case, then buy a higher quality drone.

good quality and was compatible with my GoPro Hero13. Super easy to install and works perfectly!

### ⭐⭐⭐⭐⭐ Fast, Reliable Card For 4K And Apps
*by M***E on December 9, 2025*

I picked up this SanDisk 256 GB Extreme PRO microSD card to expand storage and it has been very reliable so far. Transfers are noticeably quick when moving files, and large videos and photos load without stuttering. The read and write speeds are more than enough for 4K recording on compatible devices and for running apps or games off the card without everything feeling slow. The included adapter is handy for plugging it into a laptop or card reader when I need to move a lot of data at once. So far I have not run into corrupt files or random disconnects, which I have had with cheaper cards in the past. It formatted easily and the full capacity showed up as expected. The price is higher than basic microSD cards, but for the performance and peace of mind, it feels worth it if you are using it for important photos, video, or a handheld gaming device.
