That is exactly what I meant, So the extra speed is a waste of money, if I understand what you are saying here. Thanks for that info, so no need to spend all that money then. Great news.If the XC II is supposed to mean UHS-II bus, you don't need it. DJI is still using the UHS-I bus. The two buses are backwards compatible, much like USB 2 Vs USB 3.
Thank you for that info, so it looks like it still may be worth the extra cost of a faster speed. Do you know the cost of those two cards you mentioned, or a good supplier to get real cards from, of these?The way I approach the best choice for SD Cards for any drone cameras is to :
- first, find out the Write throughput of the camera (typically 100 Mbps for good 4K cameras)
- second, select SD cards which have a write speed equal or above that value for faster writing of your videos)
good examples of fast cards :
- Lexar Professional 1800x microSDXC --- write speed around 150 Mbps
- Integral 64GB SD video card V90 U3 Ultima Pro X2 High Endurance memory UHS-II -- write speed up 240 Mbps
Note that if you only take photos then it won't matter so much which card you use, as they will all work perfectly well.
But if you need to shoot 4K videos then you won't lose frames because your SD is too slow at saving the video.
If the SD write speed is not large enough the camera will sacrifice frames which cannot be buffered and your video may look a bit jerky.
The 2 cards mentioned above have 1.5 times to twice the write speed necessary to keep up with 4K videos.
I believe that other parameters of the SD card can be useful to look at but only converge towards enhancing that all-important write speed.
