SanDisk256GB Extreme PRO® microSD™ UHS-I Card with Adapter C10, U3, V30, A2, 200MB/s Read 140MB/s Write SDSQXCD-256G-GN6MA

Wanting a microSD card for my new 4K 2 channel dashcam, I first tried two labeled for endurance, as dashcams overwrite the same spots on a memory card a lot. However, neither was fast enough to keep up with two 4K video streams at once, whereas this card is fast enough, and being rated for such videos is also fine for use in a dashcam.One apparent problem is not with any of the cards, but rather with my desk computer. Turns out the Quicktime Player my iMac defaults to for playing .mp4 videos is not entirely compatible with 4K video files, even though it works fine for 2K video files. The fix was to instead download and use open source VLC to view the 4K files.

Great product. Package was shipping on time and no damage. I currently use the memory card for my DJI Action Pro 5 but it also comes with a MicroSD adapter that I can use on my Sony A7iii camera.

This small memory seems to be every bit as fast as the built-in memory of my Fire HD 10. I integrated it as part of the main memory. It all works really well. With this capacity, I downloaded all the music tracks, photo images, PDF files I wanted. I could also install as many Apps as I wanted from Google Playstore.

Works like a champ. One copy of my music catalog is on this disk. It's great for the car. I can put on a Playlist and use Bluetooth to send it to the car stereo. 256 gb is a ton of data. Format the memory card as portable and I can move it to a new phone when I upgrade.

AWESOME, WORKS BEST IN Y ACTION CAMERA 360X5, OR GO PRO PRIME SAVED ME $5.00 OVER STORES

I don't think you will ever need a better SD card than this one. I'm using mine to run firmware for a custom tiny computer, so it needs to be stable and handle lots of reading and writing. This is the card for that job!

So far i hame satisfied with my sandisk sd card . It seems to be working well and the transfers seem efficient. I get extreme version for the extra speed and so that it films well in the camera. So far the video camera is recording well and not stalling or slowing down. Maybe sometime ill purchase a (not extreme) to see if i notice a substantial difference in speed. difference

Works! Using to film 4k video with a gopro10
