I have P3s it doesn't take 128 GB
Can't speak for yours. I did use one in mine one time without issue. I limit the P3 to 32gb cards usually, use 64 in the P4. I have tried the samsung EVO 64 and had slow write speed notifications. Using Amplim cards at the moment. They were cheap, and I'm not doing anything critical with them so I thought I'd see how they perform. So far I haven't had any problems, and the pics/video are as good as the higher end cards as far as I can tell.

Ok a little unscientific test I just did with my two Sandisk 64 GB cards, extreme plus is U3 A1, extreme pro is U3 A2

Both transfer from micro SD to computer is the upper 160 to low 170 MB/s (fluctuates slightly during actual transfer).

I can write from computer to extreme pro at upper 90 MB/s (fluctuates) and can write to extreme plus in the 80 MB/s range.

I can transfer files from my desktop to desktop at 1.7 GB/s. It’s a NVME SSD.

I use the extreme plus in my spark, extreme pro in my P4P.

Hope that helps. Sorry for crappy pics of my desktop as the files are transferring, but just trying to add some actual real world tests to this thread. I was transferring 5 GB of data, which was what I got from a job I did recently. So I guess if i would change cards between jobs (I don’t), the 64GB is overkill. I did almost hit 32 GB one day so I got the 64 just to be in safe side. Cheap insurance. These are way cheaper than my camera’s CF cards of similar speed. 804DB7D7-5312-49E5-9074-4507F9002B10.jpeg C19CE0EF-B75D-41BA-ABB8-3468D0CC281B.jpeg 41197298-A19B-4878-A70B-24913405763F.jpeg 00E8DD4A-3324-4582-8F16-8CC3506748E7.jpeg E2F47CB5-524D-4E92-B55D-6A4CBA256BD3.jpeg

Jeez... You guys are paranoid! (I use 32s and 64s, swap with every battery change. I might be paranoid too...) ?
Just because your paranoid, it doesn’t mean they are not out to get you. ;)

I zero out my card before every flight so for me 128 is way overkill anyway. 16 is actually plenty. But I think I also use 32. I don’t want to leave tons of pic on the card without offloading. If the drone gets lost (yes, they do ;) ) then you’ve lost all your content too.
