I'd just like to point out for prospective buyers that there are two similar SanDisk Extreme SD cards, but with a key difference:
- The normal one (SDSDX3-016G-A31)
- This "HD Video" one (SDSDRX3-016G-A21)
The limitation of this card is that it normally operates at 20MB/s and only achieves 30MB/s in the few devices that support UHS-I. If your device doesn't specifically state "UHS-I", I would highly recommend paying slightly more for the far faster "normal" version. This is based on research and responses from SanDisk. Hope this helps!
(4-star rating based on the lack of clarity of this caveat in the product description. I have only purchased the other version, but hope that others aren't unaware of their devices likely not realizing their full potential using this card.)

My wife and I were so impressed with our first card that we just purchased our second Extreme HD Video card. Pictures from our Canon HD video camera are perfect using this card and all features of the camera are available. We found that using cheaper cards caused the camera to disable some recording features.

Ideal for video work
I can shoot 1920 x 1080p at 50fps rate and it never blinks. Used it to shoot a charity show with and it maintained the quality of the video for a non-stop 45 minute run! Read more

No Issues
So far this seems to be working out fine for me. I've had no problems with it. Ended up having to purchase more & some with higher capacity because of the amount of memory I use... Read more
