I purchased a SanDisk 256GB microSDXC UHS-1 Card (Speed up to 150 MB.s) for me new Mini 3 Pro but keep getting an error message the the speed of the SD card is too slow. How can that be?

Counterfeit card. Happens all too often.

I purchased it from Amazon...could it still be counterfeit ?

Hi, Exvirginian. Thank you for reaching out. Generally, this appears due to a slow SD card. If the original high-speed SD card is used, please try to format the SD card and try again. If the issue persists, please change to another SD card. Furthermore, if you are using this for Mini 3 Pro, please use one of the Recommended microSD Cards from the list below. Thank you for your kind understanding.

The camera thinks the card is too slow.
What number does the card have in a U, like this one shows U3
If it shows U1 ... that's too slow.

Yes, it could.

I have 4 SD cards, all rated for the Mini 3 & 4 Pro. I used all 4 on the M3P and never had any issues with them. Now I have a M4P and it displays this error message for all of them. I have formatted each and the message all remains.
It will record 4K videos at 60fps & 30fps, but only for 20 seconds each and then it camels the recording. I bought the drone second hand from Amazon, could there be a problem with the drone?

Hi, Bondy007. SD card writing speed is related to the current number of files stored on the SD card and how it is used by the user. If the number of files is large, the writing speed will generally be slow. If the user, for example, occasionally deletes the files on the middle of the SD card this will lead to more file system fragmentation on the SD card, so that the SD card write speed will slow down.
If the SD card writing speed is slow due to too much file fragmentation, try using a computer to format it. Have a great day ahead.

Ignore that nunsense from the AI bot moderator.
Their replies get less and less relevant.

could there be a problem with the drone?
No ... but the problem probably is that the cards are too slow.
The most recent drone models are more demanding that older ones.
